Mako Mining Corp. (TSX-V: MKO) (OTCQX: MAKOF) is pleased to report positive drill results from the Bayacun Zone within the Las Conchitas area of its wholly-owned San Albino-Murra property located in Nueva Segovia, Nicaragua. The Las Conchitas area is located approximately 2.5 kilometers south of the fully permitted San Albino gold project currently under construction.
The goal of the 2020 drill program at Las Conchitas is to focus on the most promising zones of near surface, shallow dipping, high-grade gold mineralization to delineate a maiden resource estimate. Since 2019, the Company has completed 125 shallow diamond drill holes totaling 10,484 meters within the Bayacun Zone, which is among the most promising zones within the Las Conchitas area. A total of 21,065 m within 258 holes have been drilled at Las Conchitas since the start of the 2019-20 drilling campaign.
This press release includes results for 16 holes (see table below and attached map), which were designed to further test the strike and dip extension and to improve the understanding of structural controls at the Bayacun Zone.
Akiba Leisman, Chief Executive Officer of Mako states that, “the ongoing drilling campaign at Las Conchitas continues to yield impressive results, with high grade intercepts across multiple stacked zones. The next focus of our exploration campaign will be drilling in between zones to determine if they link up. Specifically, at the Bayacun Zone we are drilling east towards the Las Dolores Zone with the objective of linking Bayacun and Las Dolores. Also, the near surface mineralized interval of 50 g/t Au in hole LC20-310 is interpreted to be the up-dip extension of the Mango Zone to the north, and we will continue drilling to find the ultimate dip potential of this zone. The presence of stacked zones/veins at Las Conchitas is consistent with the mineralization encountered at San Albino, which bodes well for defining a larger economic pit shell as we advance the target toward a maiden resource.”
Specific comments on significant drill holes reported in this press release are as follows:
LC20-310 intersected a high-grade mineralized interval of 45.79 g/t Au and 17.3 g/t Ag over 1.1 m at 97 meters from surface and confirmed a down-dip extension of the Bayacun Zone for a length of 230 m (see attached cross section). This drill hole also intersected two additional mineralized intervals (see table below and attached cross section). The deeper of the other two mineralized intervals returned 5.20 g/t Au and 2.0 g/t Ag over 3 m (2.3 m true width) and is situated at a vertical depth of 88 m from surface and approximately 9 m above the main Bayacun Zone. The other mineralized interval of 50.10 g/t Au and 40.6 g/t Ag over 0.8 m (0.8 m true width) is only 3 m below surface and is interpreted as an extension of the Mango Zone. This mineralized interval is further evidence of the presence of stacked zones at Las Conchitas and is situated 94 m above the main Bayacun Zone and 168 m to the southwest of hole LC19-70, which intersected 376.49 g/t Au over 1 m at 36 m from surface at the Mango Zone (see Mako’s press release dated May 6, 2019 and attached long section).
Multiple pending holes, including recently drilled holes at the Las Dolores Zone, have visible mineralization and will be released when assays are received.

Sampling, Assaying, QA/QC and Data Verification
Drill core was continuously sampled from inception to termination of the drill hole. Sample intervals were typically one meter. Drill core diameter was HQ (6.35 centimeters). Geologic and geotechnical data was captured into a digital database, core was photographed, then one-half split of the core was collected for analysis and one-half was retained in the core library. Samples were kept in a secured logging and storage facility until such time that they were delivered to the Managua facilities of Bureau Veritas and pulps were sent to the Bureau Veritas laboratory in Vancouver for analysis. Gold was analyzed by standard fire assay fusion, 30-gram aliquot, AAS finish. Samples returning over 10.0 g/t gold are analyzed utilizing standard Fire Assay-Gravimetric method. Due to the presence of coarse gold, the Company has used 500-gram metallic screened gold assays for analyzing samples from mineralized veins and samples immediately above and below drilled veins. This method, which analyzes a larger sample, can be more precise in high-grade vein systems containing coarse gold. All reported drill results in this press release using the metallic screening method are indicated. 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 ratio of 1 control sample per every 10 samples. Analytical results of control samples confirmed reliability of the assay data. No top cut has been applied to the reported assay results.
