GoldHaven Resources Completes Auger Drill Program at Copeçal Gold Project in Mato Grosso, Brazil
VANCOUVER, British Columbia, July 08, 2025 (GLOBE NEWSWIRE) — GoldHaven Resources Corp. ('GoldHaven' or the 'Company') (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to announce completion of its initial Auger drill program at the Copeçal Project, Brazil which commenced on June 9th, 2025. A total of 107 auger holes were successfully drilled, delivering 2,153.4 metres of subsurface coverage and marking a significant milestone in exploration efforts. The Auger drill program included 92 Auger holes which systematically covered the main area of the east anomaly on a 100m x 50m grid while a further 15 reconnaissance holes targeting geochemical – structural targets projected towards the south-east from the western anomaly. Holes were drilled from surface to the weathered rock (regolith) – fresh rock interface or to a maximum depth of 30m. The average hole depth was 20.13 meters with the hole depth range of 2m – 30m. Figure 1: Auger Drilling program completed 15 reconnaissance holes targeting geochemical – structural targets projected towards the south-east from the western anomaly Figure 2: Auger Drilling program completed 92 Auger holes which systematically covered the main area of the east anomaly on a 100m x 50m grid A total of 1,325 samples, including QAQC samples, have been shipped to ALS Global Laboratories for analysis. Sample preparation is being undertaken at ALS's facility in Cuiabá, Brazil, with final low detection fire assay analysis completed via their laboratory in Belo Horizonte, Brazil. To ensure rigorous QA/QC protocols, sampling was conducted at consistent 2-metre intervals down the drill hole. Quality control samples—including blanks, certified standards, and duplicates—were inserted at a rate of 10% of the total sample batch. These QA/QC measures adhere to industry best practices and align with the quality assurance standards of ALS Global Laboratories. Assay results are expected to be reported in late July or early August. Samples from the Auger program, which included soil – saprolite and remnant rock fragments were geologically logged to inform the ongoing preparation of a 3D geological – lithogeochemical model for the East Anomaly. Initial observations suggests that areas where the depth to bedrock exceeds 20m reflect a more pronounced, deeper regolith profile developed over potentially mineralized and hydrothermally altered areas where the bedrock granite gneiss and schist has been more highly sheared and preferentially weathered. These observations are supported by the presence of sericite alteration coincident with disseminated limonitic boxwork (after pyrite) logged in samples collected from a number of the deeper Auger holes. Rob Birmingham, CEO of GoldHaven Resources, commented: 'We are pleased to announce the successful completion of our auger drilling program at the Copeçal Gold Project, with a total of 2,153.40 meters drilled. All assay samples have been shipped for analysis. While our initial efforts were focused on the east target, we are particularly encouraged to have concluded the program by drilling the more prominent anomaly on the west target. Our attention now turns to the upcoming Very Low Frequency (VLF) electromagnetic geophysical survey, expected to commence mid-month, which will enhance our understanding of the structures within the east and west targets, as well as highlight additional prospective zones across the property.' Figure 3: Image from the Copeçal Auger Drill program highlighting completion of samples being prepared to ALS Global Laboratory VLF-EM Survey Overview Looking ahead, GoldHaven anticipates launching a Drone-borne Very Low Frequency (VLF) Electromagnetic Survey in July (referred to in Figure 4). This survey will target the structural trends believed to be favorable hosts for gold mineralization, covering both the East and West Gold-in-Soil anomalies as well as their potential strike extensions. The integration of VLF-EM geophysics with auger geochemistry will provide a robust framework for finalizing diamond drill collar locations, thereby maximizing the efficiency and effectiveness of future drilling campaigns Figure 4: Copeçal Project showing the location of the Priority East and West Targets with VLF-EM survey lines (in yellow) over AU anomalies About the Copeçal Gold Project: A Brief History The Copeçal Gold Project is strategically situated within the Alta Floresta Gold Province, a historically productive region that has yielded substantial gold discoveries since the late 1970s. GoldHaven's tenements cover a total of 3,681 hectares in a geologically favourable setting within the Juruena Gold Province of Brazil. The Juruena Gold Province, also known as the Juruena Magmatic Arc, is an orogenic belt highly prospective for mesothermal shear-related and intrusion-related gold deposits, such as G-Mining's Tocantinzinho deposit. Additionally, the region hosts recently identified porphyry-style deposits (e.g., Serabi, Jaca) and epithermal-style deposits (e.g., X1, Aura). The presence of multiple deposit styles, along with the confirmation of large-scale gold deposits in the Juruena Province of Brazil, underscores the significant potential of the Copeçal Gold Project. Recent exploration programs, including geochemical soil sampling, drone-mounted magnetometry surveys, and historical drilling data, indicate the presence of multiple gold-bearing structures. Notably, AngloGold Ashanti previously conducted systematic exploration on the property from 2010 to 2016, including auger and air-core drilling, geophysical surveys, and rock geochemistry, identifying multiple zones of anomalous gold mineralization. The Copeçal Gold Project benefits from extensive historical work, with AngloGold Ashanti's exploration confirming gold and arsenic anomalies, indicative of significant mineralization potential. Soil sampling grids and follow-up auger drilling in key areas revealed consistent gold values over wide zones, further supporting the presence of a substantial mineralized system.

Dateline Resources Reveals Significant Colosseum Gold-REE Survey Insights
Geophysics Survey Reveals Striking Similarities to World-Class Mountain Pass Rare Earth Deposit; Geochemical Anomalies Bolster Exploration Potential Dateline Resources Limited (ASX:DTR)(OTCQB:DTREF) ('Dateline' or 'the Company') is thrilled to announce the successful completion of a comprehensive magnetotelluric (MT) geophysical survey at its 100%-owned Colosseum Gold-REE Project, located in East San Bernardino County, California. The survey, finalized on June 29, 2025, with 167 stations surveyed across a 200-meter line spacing and 150-meter station spacing grid, has yielded preliminary data that closely aligns with the geophysical signature of the world-class Mountain Pass rare earth element (REE) deposit, situated just 10 km to the south. Concurrently, the ongoing geochemical sampling program is 75% complete, with initial assay results confirming anomalous REE concentrations, further enhancing the project's exploration prospects. Key Findings Successful MT Survey Completion: The MT survey concluded on schedule, with data collected using advanced 100m inline and 100m crossline electric field dipoles, paired with horizontal (x,y) magnetic field sensors at every other site and vertical (z) sensors at 25% of sites. Overnight recordings of 14-16 hours per station, supported by a remote reference site 30-40 km away, ensured high-quality data. Rigorous QA/QC checks, including preliminary 1D and 2D inversion models, have validated the dataset's integrity for upcoming 3D modelling. High-Resistivity Anomaly on Line 2200N: Preliminary 2D resistivity sections reveal an anomalous resistivity zone on survey line 2200N, extending from depth to the surface. This anomaly is precisely coincident with mapped REE-bearing fenite dykes and trachyte dykes, suggesting a resistive intrusive body or alteration zone potentially linked to carbonatite systems. Mountain Pass Analogue: The geophysical profile at Colosseum mirrors the Mountain Pass deposit's characteristic trio of anomalies: a relative gravity high, a relative magnetic low, and moderate resistivity (70-120 Ω·m). Reprocessed 2023 and 2024 gravity survey data, combined with regional magnetic data, show a gravity high and magnetic low in the fenite-bearing zone, reinforcing the Mountain Pass-like signature indicative of carbonatite-hosted REE mineralization. Geochemical Sampling Progress: As of June 30, 2025, 916 of approximately 1,200 soil and rock samples have been collected on a 60-meter spaced grid across the claim block, representing 75% completion. Initial assays from the first batch, processed by ALS Global Laboratories in Reno, Nevada, using aqua regia super trace ICP-MS analysis, have detected anomalous REE values, including cerium, lanthanum, and yttrium, above background levels. The program is on track for completion by mid-July, with full results expected later that month. Detailed Survey Insights The preliminary 2D resistivity section for line 2200N highlights a near-surface high-resistivity anomaly directly overlying fenite and trachyte dykes, which are exposed in the Colosseum pit walls and mapped north and east of the breccia pipes. This spatial correlation suggests a deep-seated resistive body, potentially a carbonatite intrusion, associated with REE mineralization. Across other survey lines, distinct resistivity contrasts indicate clay-rich alteration zones (low resistivity), possibly linked to gold-bearing breccia pipes, and higher-resistivity zones that may reflect unaltered intrusive or silicified areas. These findings align with Dateline's goal of imaging deep structures and alteration zones, with all preliminary sections under review by the technical team. Mountain Pass Geophysical Benchmark The Mountain Pass deposit, operated by MP Materials, provides a proven geophysical template for Colosseum. According to USGS studies (Peacock et al., 2021), Mountain Pass's carbonatite orebody exhibits a dense, non-magnetic core surrounded by moderately resistive host rocks. At Colosseum, the fenite-bearing zone on line 2200N corresponds with a gravity high from the 2024 survey, a magnetic low from regional datasets, and the observed intermediate resistivity. This trifecta of anomalies, consistent with carbonatite REE systems, positions Colosseum as a high-potential exploration target. The Company is integrating these findings with historical data to refine the exploration model. Geochemical Sampling Update The geochemical program, initiated in mid-June 2025, involves systematic sampling across the entire claim block, with crews collecting 0.5 kg of material per sample using GPS-guided 60-meter spacing. Samples are dried, crushed, split, and pulverized at ALS Global, with assays targeting gold, silver, REEs, and pathfinder elements. The initial results, showing REE anomalies, are a critical early indicator of mineralization. Once all 1,200 samples are assayed, Dateline will generate geochemical anomaly maps to identify multi-element clusters, integrating these with geophysical data to prioritize drill targets. Next Steps Dateline is transitioning to the data integration and target definition phase, with the following planned activities: 3D MT Inversion Modelling: A full 3D resistivity model will be developed using dual inversion approaches. A Colorado-based multi-physics team will employ a proprietary 3D inversion code, while a Perth, Australia, team will use the ModEM MT inversion software. This dual approach, expected to be completed in a few weeks, will cross-validate results and enhance subsurface imaging. Geochemical Completion: The remaining 284 samples will be collected and assayed by mid-July, with comprehensive interpretation to follow. Anomaly maps for cerium, lanthanum, yttrium, and other REEs will guide target delineation. Integrated Targeting and Drill Program: The 3D MT model, complete geochemical dataset, and reprocessed gravity/magnetic data will be layered to identify coincident anomalies. High-priority targets exhibiting the Mountain Pass-like signature (gravity high, magnetic low, intermediate resistivity) will be slated for drilling. The planned campaign will test both REE potential in the carbonatite target and remaining gold resources in the breccia pipes, with updates to follow upon target finalization.
