Orosur Mining Inc Announces Infill Drilling Hits 104m @ 6.61g/t Au at Pepas
Assays from three more holes from the Pepas MRE infill program: PEP047 - 104m @ 6.61g/t Au from surface PEP048 - 32.3m @ 3.65g/t Au from surface PEP049 - 94.2m @ 3.74g/t from surface Soil sampling about to recommence at El Cedro LONDON, UK / / August 5, 2025 / Orosur Mining Inc. ("Orosur" or the "Company") (TSXV:OMI)(AIM:OMI), is pleased to announce an update on the progress of exploration activities at the Company's flagship, 100% owned, Anzá Gold Project ("Project") in Colombia. As announced on 14th July 2025, the Company has taken the formal decision to commence infill drilling at its Pepas gold prospect, with the target of moving Pepas to a NI43-101 compliant Mineral Resource Estimate (MRE) by the end of the year. The first several holes of this program (announced 17th July 2025), vindicated this decision by returning exceptional widths and grades, especially hole PEP045 which returned 62.3m @ 12.76g/t Au. A drill program has been designed in conjunction with external consultants to facilitate an MRE being calculated. This program has been designed with the multiple objectives of infilling previous drilling, expanding beyond current drilling to define the boundaries, and understanding the geological controls upon mineralisation and the variations in geology and grade across the deposit. Holes will be drilled in an order that attempts to address these issues concurrently. As a result of the shallow nature of mineralisation, holes are generally short, taking between three and four days to complete on average. When the Company reassumed control of the Project in December 2024, samples were shifted to a fire-assay laboratory facility in Medellin, that has consistently provided 3-4 days turnaround of assay results. The Company is thus currently averaging roughly one hole per week with only one rig - an exceptionally fast rate of progress by industry standards. These three holes announced today are a continuation of this infill program and have all returned exceptional results (most especially PEP047), with thick sequences of high-grade gold mineralisation commencing from surface.

Latest drill Intercepts, Pepas Prospect Infill drilling is ongoing, but the recent holes are already beginning to provide greater understanding of the genesis of Pepas and, as importantly, grade distribution which will be vital for mine planning studies. While drilling continues, in the near term, the Company will soon begin to undertake additional studies on such issues as metallurgy, mining planning and logistics, so that Pepas can be advanced as quickly as possible post its maiden MRE. Figure 2. Plan of holes Figure 3. Section, PEP047 Figure 4. Section PEP048 and PEP049 El Cedro The El Cedro prospect is a large gold porphyry system, located toward the south of the Anzá project, on the same granted EL as the Pepas and APTA deposits. As previously announced (28th May 2025), the Company had commenced a large soil sampling program at El Cedro, designed to expand upon previous work by Anglo American and the Company's previous JV partner. This sampling program was roughly 1/3 complete when it had to be suspended due to road damage sustained from an unusually wet season in the region. Rains have now abated, and this road damage has been repaired such that Company geological crews will be returning to El Cedro this week to recommence this program. Orosur CEO Brad George commented: "The latest results at Pepas continue to impress. While size remains to be defined, the picture of Pepas as a highly lucrative mining proposition is rapidly solidifying. We are increasingly confident that there is a commercially viable opportunity at Pepas and so we will very soon commence non-drill related studies to begin the process of advancing Pepas toward development." Colombia - ANZÁ Project The Anzá Project is now 100% owned by the Company following completion of a Share Purchase Agreement ("SPA"), announced 28th November 2024, whereby the Company purchased all of the shares of its previous JV partner; Minera Monte Aguila ("MMA"). The Project, which is located 50km west of Medellin, is easily accessible and boasts excellent infrastructure including water, power and communications as well as a large exploration camp. From September 2018 to November 2024, the Anzá Project was under the control of its previous JV partner MMA, itself a 50/50 venture between the world's two largest gold miners, Agnico Eagle Mines and Newmont Mining. Prospects The Company is currently focussed on three prospects within the Anzá Project - Pepas, APTA and El Cedro. All three prospects are within the same granted exploration title that is broken into two, non-contiguous pieces (Figure 2). Drilling is currently being undertaken at the Pepas prospect in the northern extent of the Anzá Project (pre-acquisition) over 10km north of the central base camp at APTA. In parallel, mapping and sampling is being undertaken over the El Cedro porphyry system in the south of the project area. Figure 5.

Orosur Drills 62.3m @ 12.76g/t Au at Pepas
Orosur Mining Inc - Exceptional results at Pepas LONDON, GB / ACCESS Newswire / July 17, 2025 / Orosur Mining Inc. ('Orosur' or the 'Company') (TSXV:OMI)(AIM:OMI), is pleased to announce an update on the progress of exploration activities at the Company's flagship Anzá Project ('Project') in Colombia. Colombia - ANZÁ Project The Anzá Project is now 100% owned by the Company following completion of a Share Purchase Agreement ('SPA'), announced 28th November 2024, whereby the Company purchased all of the shares of its previous JV partner; Minera Monte Aguila ('MMA'). The Project, which is located 50km west of Medellin, is easily accessible and boasts excellent infrastructure including water, power and communications as well as a large exploration camp. The Project sits within the prolific mid-Cauca belt, Colombia's primary gold belt, and is located along strike between several world class gold/copper deposits including Buritica, Quebradona and Guayabales/Marmato (Figure 1). From September 2018 to November 2024, the Anzá Project was under the control of its previous JV partner MMA, itself a 50/50 venture between the world's two largest gold miners, Agnico Eagle Mines and Newmont Mining. Figure 1. Mid-Cauca Belt Prospects The Company is currently focussed on three prospects within the Anzá Project - Pepas, APTA and El Cedro. All three prospects are within the same granted exploration title that is broken into two, non-contiguous pieces (Figure 2). Drilling is currently being undertaken at the Pepas prospect in the northern extent of the Anzá Project (pre-acquisition) over 10km north of the central base camp at APTA. In parallel, mapping and sampling is being undertaken over the El Cedro porphyry system in the south of the project area. Figure 2. Main prospects, licences pre-MMA acquisition Pepas Prospect Pepas was discovered by MMA in late 2021 by BLEG sampling and geological mapping, followed by 11 diamond drill holes in 2022 (PEP001 to PEP011). After completion of the transaction to buy MMA ('Transaction'), the Company restarted drilling at Pepas in late-November 2024. Drilling commenced with hole PEP012, which was positioned to confirm previous high-grade results in holes PEP001, PEP005 and PEP007 drilled in 2022. Figure 3. Plan of holes Drilling at Pepas, post Transaction, has largely concentrated on a small central core, where a body of high-grade gold mineralisation is being defined from surface. Additional drilling has also been undertaken around this central core to understand the wider geological context and as the commencement of a larger scale exploration program. Of the nine holes discussed in this announcement, six (PEP038 to PEP043) were drilled around but outside the Pepas core, while three (PEP044 to PEP046) have been drilled as part of the previously announced infill program that is designed to move Pepas to a Mineral Resource Estimate (MRE). PEP038 was drilled to the north at what is referred to as Pepas North. This was the third of three holes drilled here as the first move to this area, following up positive surface geochemical results. This hole was drilled orthogonal to the two previous holes, to provide the maximum lithological and structural information. PEP038 returned a result of 16.8m @ 0.68g/t Au. As with the two previous holes in this vicinity, this hole demonstrates the scale of the epithermal system that hosts Pepas and has provided valuable information to understand the controls of this system. PEP039 was a speculative exploration hole drilled a substantial distance to the south and west of the Pepas core, following up zones of surface silicification. No substantial results were returned. PEP040 was drilled outside the known Pepas envelope to the SW, to test lower-level shallow mineralisation previously identified by earlier drilling. The hole returned a small intersection of 10.25m @ 1.35g/t Au from surface (figure 4) that indicates the potential for a body of satellite mineralisation, adjacent to the Pepas core, that will require additional follow up. Figure 4. PEP040 and PEP046 section PEP041 was drilled outside the currently known Pepas envelope to the north to test the northward extension of the mineralisation first identified by earlier drilling undertaken by the Company's previous JV partner MMA. This hole returned a positive intersection of 31.75m @ 2.01 g/t Au, opening this area for potential extension (figure 5). Figure 5. PEP041 Section PEP042 was drilled to the NE of the currently known central core of mineralisation as a conceptual hole to test geophysical zones that were identified by the recent airborne magnetic survey. No surface geochemical work has yet been undertaken in this area. Several thin zones of encouraging gold mineralisation were encountered in this hole, well outside the known mineralised core (figure 6). This result has substantially increased the potential of this area and will now be followed up with surface mapping and sampling, and potentially later drilling. Figure 6. PEP042 Section PEP043 was drilled outside the known mineralised envelope to test areas of surface silicification. No substantial intersections were recorded Holes PEP044, PEP045 and PEP045 were all drilled as part of the previously announced MRE infill program at Pepas. A plan for this program has been developed to infill Pepas to sufficient degree to potentially allow a high level (measured and indicated) MRE to be calculate, but also to assist in understanding the controls upon mineralisation and to better define the very high-grade zones that have the potential to add substantial ounces. Results from these holes were exceptional, with PEP044 returning 38.5m @ 6.01g/t Au, PEP045 returning 62.3m @ 12.76g/t Au and PEP046 returning 53.2m @ 3.36g/t Au (figures 4 and 7). The Company feels these results vindicate its decision to begin the resource drilling phase at Pepas, with these exceptionally thick, and high-grade results, substantially upgrading the potential for contained ounces beyond what had been assumed at the commencement of the process. In addition, the results, particularly that of PEP045, have provided valuable insight to the primary controls upon this mineralisation, suggestive of the main feeder zone being a series of steeply dipper structures along the SW margin of the zone. The depth extent implications of this theory will be tested in later drilling Figure 7. PEP044 and PEP045 section Drill intersections for these most recent holes are as follows: Table 1. Latest drill Intercepts, Pepas Prospect Geological Modelling As previously announced, Company geological teams, in cooperation with an external consultant are currently engaged in a comprehensive review and reinterpretation of all drilling undertaken on the Anzá project since its inception in roughly 2012, with particular focus on the APTA and Pepas prospects as these both have near-term resource potential. The results thus far are highly encouraging, with recent insights suggesting substantively different genetic theories to that put forward by the previous owners of the ANZÁ project and the Company's previous JV partner. These concepts are being finalised now, which will lead to exploration plans being formalised to run in parallel with the ongoing resource infill program at Pepas. Holes Drilled post MMA Transaction 26 holes have been drilled at Pepas since the MMA Transaction in November 2024. Assay results are tabulated below. Table 2. Results to date, post MMA Transaction Orosur CEO Brad George commented: 'The latest results at Pepas are exciting. Not only do we continue to expand the area of potential that will require drill follow-up, but the commencement of resource drilling has exceeded all expectations, with some of the thickest and highest grade intersections seen anywhere in the world. We have only just begun.'

Orosur Mining Inc Announces Pepas Moving into MRE Drilling Programme
Orosur Mining Inc - Pepas moving into Mineral Resource Estimate drilling within wider exploration programme LONDON, UK / ACCESS Newswire / July 14, 2025 / Orosur Mining Inc. ('Orosur' or the 'Company') (TSXV:OMI)(AIM:OMI), is pleased to announce an update on the progress of exploration activities at the Company's flagship Anzá Project ('Project') in Colombia. The Company announces that it has taken the formal decision to begin a work program that, if successful, is designed to allow a Mineral Resource Estimate (MRE) to be calculated at its Pepas gold prospect, within the Anzá gold project area in Colombia. This decision has been taken on the basis of external conceptual studies that suggest the location and physical characteristics of the gold mineralisation so far defined at Pepas, in the context of record high gold prices, may offer potential nearer term production opportunities. This decision does not stop exploration at Pepas, the wider Anzá project or the Company's El Pantano project in Argentina. The Company is confident that both exploration and resource definition streams can be run in parallel within the limits of the Company's financial, human and technical resources. The primary impact is that the single drill rig currently employed on the Project has been diverted toward infill drilling within the current boundary of known high grade gold mineralisation at Pepas. During this time, geological studies and additional surface field work will be undertaken at Pepas and other prospects so that targets are ready for the rig to move back to regional exploration once the resource infill is completed. Colombia - ANZÁ Project The Anzá Project is now 100% owned by the Company following completion of a Share Purchase Agreement ('SPA'), announced 28th November 2024, whereby the Company purchased all of the shares of its previous JV partner; Minera Monte Aguila ('MMA'). The Project, which is located 50km west of Medellin, is easily accessible and boasts excellent infrastructure including water, power and communications as well as a large exploration camp. The Project sits within the prolific mid-Cauca belt, Colombia's primary gold belt, and is located along strike between several world class gold/copper deposits including Buritica, Quebradona and Guayabales/Marmato (Figure 1). From September 2018 to November 2024, the Anzá Project was under the control of its previous JV partner MMA, itself a 50/50 venture between the world's two largest gold miners, Agnico Eagle Mines and Newmont Mining. Figure 1. Mid-Cauca Belt Prospects The Company is currently focussed on three prospects within the Anzá Project - Pepas, APTA and El Cedro. All three prospects are within the same granted exploration title that is broken into two non-contiguous pieces (Figure 2). Drilling is currently being undertaken at the Pepas prospect in the northern extent of the Anzá Project (pre-acquisition) over 10km north of the central base camp at APTA. In parallel, mapping and sampling is being undertaken over the El Cedro porphyry system in the south of the project area. Pepas and North Pepas Prospects The Pepas prospect is in the far north of the Anzá project and was discovered by the Company's previous JV partners, MMA, in late 2021 by BLEG sampling and geological mapping, followed by 11 diamond drill holes in 2022 (PEP001 to PEP011). After completion of the transaction to buy MMA, the Company restarted drilling at Pepas in late-November 2024. Drilling commenced with hole PEP012, which was positioned to confirm previous high-grade results in holes PEP001, PEP005 and PEP007 drilled in 2022. Since reassuming control of the Project in December 2024, the Company has released assay results from 26 holes (PEP012 to PEP037), most of which were concentrated in and around the central core of near-surface high-grade gold mineralisation. Figure 3. Plan of holes, core Pepas zone. This small, but thick and high-grade zone of mineralisation has developed very quickly since the Company reassumed control, and while the surrounding areas remain largely unexplored, the Company feels that what has thus far been defined is worthy of economic study, especially in the current gold price environment. Geological Modelling and Economic Studies As previously announced, encouraged by the exceptional results at the Pepas prospect, the Company has begun the process of geological modelling and preliminary economic assessment at Pepas. The characteristics of Pepas that encouraged the Company to begin the process of conceptual study are its high grade, surficial nature, thickness, availability of power to site, proximity to the main regional highway without having to pass through villages, and the existence of numerous nearby mines and processing facilities that might offer the opportunity for third party toll treating. The Company carried out its own internal geological resource models and high-level concept studies, the results of which the Company felt were sufficiently positive that it then engaged an external mineral consulting firm to model preliminary pit shells in order to assess if Pepas warranted further study. The results of this high-level conceptual study were positive and have led to the Company making the formal decision to examine Pepas in more detail, with the ultimate objective of determining if a near term production option can be developed at Pepas in its current form. Resource Drilling The first stage in this process is the creation of a Mineral Resource Estimate (MRE) at Pepas, that can then be used as the basis for later economic evaluation. To that end, one of the outputs of recent work was the development of an infill drilling plan that, if successful, could be sufficient to allow an MRE to be calculated. Ultimately, the amount of drilling required to develop an MRE will be subject to results and may be modified during the infill drilling process. However, at this preliminary stage, the Company feels that between 1,500m and 2,000m of additional drilling should be sufficient. The single drill rig that the Company has on site at Anzá, has been moved back to infill drilling at Pepas. On current production rates, it is expected that this plan should be completed in November 2025, assuming no major modifications being necessary following analysis of results. Once completed, subject to results and the availability of consultants for the required QAQC visits to the Project, the Company is targeting December 2025 for completion of this process and publishing of an MRE at Pepas. Geological Assessment In addition to drilling information, an MRE, in accordance with NI43-101, also requires a robust and defensible geological model to underpin the interpolation and extrapolation of information between and beyond drill holes. To date, the Company has not been able to develop such a model at Pepas due to the speed with which drilling and results have progressed since the Company reassumed control in December 2024. Drilling thus far has focussed on defining a shallow, potentially economic orebody, with Company drilling since December 2024 limited to some 80m vertical depth. To satisfy this MRE requirement, an external geological consultant, specialising in structural geology and metamorphic petrology, has travelled to the Anzá project to spend several weeks with Company geological staff examining all of the historical drilling undertaken at Pepas and APTA since the Company acquired the project in late 2014. The objectives of this visit and program are three-fold: 1. Develop a geological model to underpin a potential MRE at Pepas. 2. Understand the wider Pepas epithermal system, and in particular, define the litho-structural controls upon the exceptionally high-grade mineralised zone at Pepas and plan a targeting methodology to guide exploration toward finding repetitions and source feeder zones. 3. Develop a geological model to explain the controls upon the very high-grade mineralisation historically defined at the APTA deposit at Anzá to facilitate an MRE being defined at APTA. APTA The APTA deposit lies in the centre of the Anzá project and has been the subject of most exploration activity on the project, with some 38,000 metres of drilling having been completed. APTA is thought to be a hybrid mineralised system with an earlier VMS system being overprinted by later epithermal events. However, most historical work at APTA has been undertaken either by the Company's predecessor (Waymar Resources) or by its previous JV partner (MMA), both of which focussed on drilling, with minimal geological interpretation. Numerous thick, high-grade gold intersections have been recorded at APTA (Table 2), that have defined several distinct high-grade ore pods, separated by lower grade halo material. Internal and external modelling have suggested that a NI43-101 MRE could potentially be possible at APTA as it stands now, but with limited understanding of the controls upon these high-grade pods, any MRE would be conservative. Therefore, one of the objectives of the current geological site visit by, is to work with internal geological teams to better understand these high-grade zones and so allow any future MRE to better reflect the impact of these zones. An outcome of this geological study may be the recommendation for more drilling to underpin this new geological model, and as such any move toward an MRE will be dependent upon outcomes of this study and any subsequent work programs. Wider Exploration Work As noted, moving Pepas toward an MRE is not a fundamental shift in the Company's direction, but rather a temporary adjustment to drilling priorities for several months. While this process is underway, field mapping and sampling will continue at other prospects in readiness for the rig moving back to exploration once the infill is complete. Drilling at Pepas North and elsewhere in the Pepas region has indicated that Pepas is part of a much larger epithermal system consisting of wider scale low grade halo mineralisation and at least one discrete high-grade pod. One stated outcome of the current geological visit is to derive an understanding of the controls upon the high-grade zones, and as importantly, the likely source feeder zones. The outcome of this study will likely be a work program of surface sampling and mapping that may provide drill targets around Pepas. As announced, soil sampling at the El Cedro porphyry system at Anzá has been delayed due to seasonal rains and road access issues. Sampling will recommence once access has been reestablished. The Company's early stage El Pantano gold exploration project in Argentina is drill ready. The Company is currently negotiating with local drill companies and examining options for camps, with a view to commencing drilling before the end of the calendar year.

Orosur Mining Inc Announces Pepas Moving into MRE Drilling Programme
Orosur Mining Inc - Pepas moving into Mineral Resource Estimate drilling within wider exploration programme Orosur moving to parallel streams - exploration and resource drilling. Rig now infill drilling Pepas as precursor to MRE. Decision based on positive conceptual studies. Geological consultants on site to develop required geological models for both Pepas and APTA. LONDON, UK / / July 14, 2025 / Orosur Mining Inc. ("Orosur" or the "Company") (TSXV:OMI)(AIM:OMI), is pleased to announce an update on the progress of exploration activities at the Company's flagship Anzá Project ("Project") in Colombia. The Company announces that it has taken the formal decision to begin a work program that, if successful, is designed to allow a Mineral Resource Estimate (MRE) to be calculated at its Pepas gold prospect, within the Anzá gold project area in Colombia. This decision has been taken on the basis of external conceptual studies that suggest the location and physical characteristics of the gold mineralisation so far defined at Pepas, in the context of record high gold prices, may offer potential nearer term production opportunities. This decision does not stop exploration at Pepas, the wider Anzá project or the Company's El Pantano project in Argentina. The Company is confident that both exploration and resource definition streams can be run in parallel within the limits of the Company's financial, human and technical resources. The primary impact is that the single drill rig currently employed on the Project has been diverted toward infill drilling within the current boundary of known high grade gold mineralisation at Pepas. During this time, geological studies and additional surface field work will be undertaken at Pepas and other prospects so that targets are ready for the rig to move back to regional exploration once the resource infill is completed. Colombia - ANZÁ ProjectThe Anzá Project is now 100% owned by the Company following completion of a Share Purchase Agreement ("SPA"), announced 28th November 2024, whereby the Company purchased all of the shares of its previous JV partner; Minera Monte Aguila ("MMA"). The Project, which is located 50km west of Medellin, is easily accessible and boasts excellent infrastructure including water, power and communications as well as a large exploration camp. The Project sits within the prolific mid-Cauca belt, Colombia's primary gold belt, and is located along strike between several world class gold/copper deposits including Buritica, Quebradona and Guayabales/Marmato (Figure 1). From September 2018 to November 2024, the Anzá Project was under the control of its previous JV partner MMA, itself a 50/50 venture between the world's two largest gold miners, Agnico Eagle Mines and Newmont Mining. Figure 1. Mid-Cauca Belt ProspectsThe Company is currently focussed on three prospects within the Anzá Project - Pepas, APTA and El Cedro. All three prospects are within the same granted exploration title that is broken into two non-contiguous pieces (Figure 2). Drilling is currently being undertaken at the Pepas prospect in the northern extent of the Anzá Project (pre-acquisition) over 10km north of the central base camp at APTA. In parallel, mapping and sampling is being undertaken over the El Cedro porphyry system in the south of the project area. Pepas and North Pepas ProspectsThe Pepas prospect is in the far north of the Anzá project and was discovered by the Company's previous JV partners, MMA, in late 2021 by BLEG sampling and geological mapping, followed by 11 diamond drill holes in 2022 (PEP001 to PEP011). After completion of the transaction to buy MMA, the Company restarted drilling at Pepas in late-November 2024. Drilling commenced with hole PEP012, which was positioned to confirm previous high-grade results in holes PEP001, PEP005 and PEP007 drilled in 2022. Since reassuming control of the Project in December 2024, the Company has released assay results from 26 holes (PEP012 to PEP037), most of which were concentrated in and around the central core of near-surface high-grade gold mineralisation. Figure 3. Plan of holes, core Pepas zone. This small, but thick and high-grade zone of mineralisation has developed very quickly since the Company reassumed control, and while the surrounding areas remain largely unexplored, the Company feels that what has thus far been defined is worthy of economic study, especially in the current gold price environment. Geological Modelling and Economic StudiesAs previously announced, encouraged by the exceptional results at the Pepas prospect, the Company has begun the process of geological modelling and preliminary economic assessment at Pepas. The characteristics of Pepas that encouraged the Company to begin the process of conceptual study are its high grade, surficial nature, thickness, availability of power to site, proximity to the main regional highway without having to pass through villages, and the existence of numerous nearby mines and processing facilities that might offer the opportunity for third party toll treating. The Company carried out its own internal geological resource models and high-level concept studies, the results of which the Company felt were sufficiently positive that it then engaged an external mineral consulting firm to model preliminary pit shells in order to assess if Pepas warranted further study. The results of this high-level conceptual study were positive and have led to the Company making the formal decision to examine Pepas in more detail, with the ultimate objective of determining if a near term production option can be developed at Pepas in its current form. Resource DrillingThe first stage in this process is the creation of a Mineral Resource Estimate (MRE) at Pepas, that can then be used as the basis for later economic evaluation. To that end, one of the outputs of recent work was the development of an infill drilling plan that, if successful, could be sufficient to allow an MRE to be calculated. Ultimately, the amount of drilling required to develop an MRE will be subject to results and may be modified during the infill drilling process. However, at this preliminary stage, the Company feels that between 1,500m and 2,000m of additional drilling should be sufficient. The single drill rig that the Company has on site at Anzá, has been moved back to infill drilling at Pepas. On current production rates, it is expected that this plan should be completed in November 2025, assuming no major modifications being necessary following analysis of results. Once completed, subject to results and the availability of consultants for the required QAQC visits to the Project, the Company is targeting December 2025 for completion of this process and publishing of an MRE at Pepas. Geological AssessmentIn addition to drilling information, an MRE, in accordance with NI43-101, also requires a robust and defensible geological model to underpin the interpolation and extrapolation of information between and beyond drill holes. To date, the Company has not been able to develop such a model at Pepas due to the speed with which drilling and results have progressed since the Company reassumed control in December 2024. Drilling thus far has focussed on defining a shallow, potentially economic orebody, with Company drilling since December 2024 limited to some 80m vertical depth. To satisfy this MRE requirement, an external geological consultant, specialising in structural geology and metamorphic petrology, has travelled to the Anzá project to spend several weeks with Company geological staff examining all of the historical drilling undertaken at Pepas and APTA since the Company acquired the project in late 2014. The objectives of this visit and program are three-fold:1. Develop a geological model to underpin a potential MRE at Pepas.2. Understand the wider Pepas epithermal system, and in particular, define the litho-structural controls upon the exceptionally high-grade mineralised zone at Pepas and plan a targeting methodology to guide exploration toward finding repetitions and source feeder zones.3. Develop a geological model to explain the controls upon the very high-grade mineralisation historically defined at the APTA deposit at Anzá to facilitate an MRE being defined at APTA. APTAThe APTA deposit lies in the centre of the Anzá project and has been the subject of most exploration activity on the project, with some 38,000 metres of drilling having been completed. APTA is thought to be a hybrid mineralised system with an earlier VMS system being overprinted by later epithermal events. However, most historical work at APTA has been undertaken either by the Company's predecessor (Waymar Resources) or by its previous JV partner (MMA), both of which focussed on drilling, with minimal geological interpretation. Numerous thick, high-grade gold intersections have been recorded at APTA (Table 2), that have defined several distinct high-grade ore pods, separated by lower grade halo material. Internal and external modelling have suggested that a NI43-101 MRE could potentially be possible at APTA as it stands now, but with limited understanding of the controls upon these high-grade pods, any MRE would be conservative. Therefore, one of the objectives of the current geological site visit by, is to work with internal geological teams to better understand these high-grade zones and so allow any future MRE to better reflect the impact of these zones. An outcome of this geological study may be the recommendation for more drilling to underpin this new geological model, and as such any move toward an MRE will be dependent upon outcomes of this study and any subsequent work programs. Wider Exploration WorkAs noted, moving Pepas toward an MRE is not a fundamental shift in the Company's direction, but rather a temporary adjustment to drilling priorities for several months. While this process is underway, field mapping and sampling will continue at other prospects in readiness for the rig moving back to exploration once the infill is complete. Drilling at Pepas North and elsewhere in the Pepas region has indicated that Pepas is part of a much larger epithermal system consisting of wider scale low grade halo mineralisation and at least one discrete high-grade pod. One stated outcome of the current geological visit is to derive an understanding of the controls upon the high-grade zones, and as importantly, the likely source feeder zones. The outcome of this study will likely be a work program of surface sampling and mapping that may provide drill targets around Pepas. As announced, soil sampling at the El Cedro porphyry system at Anzá has been delayed due to seasonal rains and road access issues. Sampling will recommence once access has been reestablished. The Company's early stage El Pantano gold exploration project in Argentina is drill ready. The Company is currently negotiating with local drill companies and examining options for camps, with a view to commencing drilling before the end of the calendar year.
