VANCOUVER, BC / ACCESS Newswire / May 21, 2025 / Mako Mining Corp. (TSXV:MKO)(OTCQX:MAKOF) ('Mako' or the 'Company') is pleased to report initial results from the 2025 reverse circulation (RC) drill program at the El Golfo area within the El Jicaro Concession located immediately south of the company's 100% owned Las Conchitas and San Albino Gold Mines in Nicaragua (please see Figure 1 below).
The 2025 exploration program at El Golfo comprises an initial 3,000 metres of RC drilling and is part of the Company's regional drill program on its district-scale, underexplored land package of 224 km2, including the recently granted Tiburon concession to the east.
Drill hole EJ25-RC53 (270/-60) intersected a wide, high-grade interval (see table below) of 39.15 g/t Au and 27.8 g/t Ag over 8.0 m (5.9 m ETW), 19.2 m below surface. Hole EJ25-RC53 tested a prominent NE-SW oriented structure interpreted from geochemical soil sampling and geological mapping of underground workings which the Company initiated late last year after being granted access for the first time in 15 years from the local landowner. This structural orientation is known to control gold mineralization at the San Albino and Las Conchitas deposits. Drill hole EJ25-RC52 (0/-90), drilled from the same drill pad, intersected a strongly sheared and disturbed zone with anomalous gold values.
The Company has completed 12 drill holes in the past month, targeting the Pavona zone, one of several drill targets situated within the El Golfo area. The other 10 drill holes of the initial drill program have also intersected zones with sulfide mineralization interpreted to be part of the same gold-bearing system. Assay results of these drill holes are pending and will be released as they become available. The detailed mapping and sampling campaign continues to define new drill targets on this 1.5 km2 area. El Golfo has had no previous drilling, and has excellent exploration potential. El Golfo is located less than a kilometer from the pits currently being mined at Las Conchitas and processed at the 500 tonne per day San Albino plant.
Akiba Leisman, CEO of Mako states 'it is encouraging that we hit one of the highest grade-thickness intervals we have ever hit on the second hole at one of the highest priority targets on the 224 km2 San Albino Project. El Golfo is the area within our concessions that has had the most historical mining since the 18th century, but due to access and logistical constraints, we initially focussed on the Las Conchitas target, after the San Albino Mine was put into commercial production in 2021. Now that we have started a relatively significant exploration program at El Golfo, we are optimistic that El Golfo will potentially turn into a new mining area for us.'
History1
The El Golfo area encompasses the southwest extension of mineralized structures found at the Las Conchitas deposit, located less than a kilometre to the north (see attached map). Gold bearing structures were discovered at the historic El Golfo Mine area by Spaniards in the late 18th century. Underground mining activity at El Golfo continued until 1915 when a flood destroyed a wooden dam and part of the mill. Prior to flooding, the El Golfo mill was a stamp mill with 20 - 500 pound stamps, processing material with a mill head grade of 21.56 g/t Au (0.63 oz/t). Underground workings were flooded and later collapsed which consequently ended all activities at the mine.
It was reported that a total of sixteen gold bearing veins were outlined by surface and underground workings with individual veins having a strike length of up to 150 meters and vein widths ranging from 5 cm to 4.5 m. Mineralization is similar to that being mined at San Albino which consists of quartz veins containing galena, sphalerite, arsenopyrite and occasionally visible gold accompanied by lesser silver mineralization.
New Tiburon Concession
The Company's wholly-owned Nicaraguan subsidiary, Nicoz Resources, S.A., has been granted a new concession by the Nicaraguan Ministry of Mines and Energy ('MEM'). The new concession, called Tiburon, covers an area of 3,605 hectares (36.05 km2) and is contiguous to the east and northeast of the Company's San Albino-Murra and El Jicaro concessions, respectively.
The Tiburon concession allows for both exploration and exploitation and is valid for a period of 25 years, until November 2049.
The Company now holds 100% of five mineral concessions in Nueva Segovia, Nicaragua for a total land package of approximately 22,422 hectares (224 km2).

Sampling, Assaying, QA/QC and Data Verification
All reverse circulation (RC) holes were drilled dry i.e above the water table and no water or other fluids were injected into the hole. RC drill samples were collected every 1 meter using a center-return hammer and samples were obtained from a Gilson chip splitter which is cleaned using compressed air after each sample. Samples were bagged and labeled at the drill site under a geologist's supervision and are logged on site by a geologist who visually selects potential mineralized intervals for fire assay. The mineralized interval(s) including 3-5 samples above and below, the selected interval are continuously sampled and shipped to the Bureau Veritas Lab (BV) in Managua, respecting the best chain of custody practices. Pulps are sent by Bureau Veritas to their laboratory in Vancouver under their chain of custody for analysis. Gold was analyzed by standard fire assay fusion, 30 gr aliquot, AAS finish. Samples returning over 10.0 g/t gold are analyzed utilizing standard Fire Assay-Gravimetric method. The Company follows industry standards in its QA&QC procedures. Control samples consisting of duplicates, standards and blanks were inserted into the sample stream at a minimum ratio of 1 control sample per every 10 samples. Analytical results of control samples confirmed reliability of the assay data.
