Drilling at Las Conchitas South Intersects 138.29 g/t Au Over 1.3m Estimated True Width Extending the High Grade Mango Zone to 213m Down Dip

VANCOUVER, BC, March 17, 2022 /PRNewswire/ - Mako Mining Corp. (TSXV: MKO) (OTCQX: MAKOF) ("Mako" or the "Company") is pleased to report positive drill results from the Las Conchitas-South (LC-S) area of its wholly-owned San Albino-Murra property located in Nueva Segovia, Nicaragua. The LC-S area is located approximately 2.5 kilometers ("km") south of the San Albino gold mine ("San Albino") which is currently in commercial production.

Highlights of the drilling

• 138.29 g/t Au and 99.0 g/t Ag over 1.45m (1.3m Estimated True Width ("ETW")) intersected in LC21-432
• 74.31 g/t Au and 38.1 g/t Ag over 0.80 m (0.7m ETW), intersected in LC21-415
• 31.00 g/t Au and 14.9 g/t Ag over 1.00 m (0.8 ETW), intersected in LC21-419

The LC-S area is comprised of four mineralized zones, Las Dolores, Bayacun, Mango and El Limon. The objective of the LC-S drilling campaign reported in this press release was to further test the strike and dip extensions of the Mango Zone.

Drill hole LC21-432 intersected an interval of 138.29 g/t Au and 99.0 g/t Ag over 1.45 m (1.3m ETW) at 68.75m from surface (see attached cross section). This hole confirmed the down dip extension of the high-grade mineralization within the Mango zone where hole LC19-70 intersected 376.49 g/t Au over 1m (see press release on May 6, 2019).

The intercept in hole LC21-432 is also 213m down dip from LC19-Tunnel-2, a historical working at surface. Vertical sampling of the vein at LC19-Tunnel-2 yielded 1.5m @ 25.92 Au and 42.0 Ag; 1.5m @ 21.71 Au and 49.1 Ag and 1.3m @ 54.17 Au and 57.5 Ag.

LC21-435 intersected two mineralized intervals. The upper interval of 6.44 g/t Au and 14.7 g/t Ag over 0.50 m ETW, at 126.3m from the surface, is interpreted to be the down dip extension of Mango Zone 2, which was exposed in trench LC11-TR-07 approximately 395m up dip. The lower interval of 12.38 g/t Au and 22.7 g/t Ag over 2.60 m (2.0 ETW), at 149.0m from surface, is interpreted to be an extension of the Upper Bayacun Zone over 440m down dip.

LC21-415 was designed to test the strike extension of the Mango Zone. It intersected an interval of 74.31g/t Au and 38.1g/t Ag over 0.80m (0.7m ETW), 43.3m from surface, and it represents a 30m strike extension from a high-grade interval in hole LC11-01 which intersected 62.96 g/t Au and 61.7 g/t Ag over 3.0m (see press release dated February 22, 2012).  LC21-415 is also interpreted to be a 100m strike extension from the previously described surface exposure in LC19-Tunnel-2.

LC21-419 tested and confirmed mineralization for an additional 133m towards the northeast. This drill hole intersected an interval of 31.00 g/t Au and 14.9 g/t Ag over 1.00m (0.8m ETW), 25m from surface.

Akiba Leisman, CEO of Mako states that "these are extraordinary results at LC – S. These organically funded exploration results are showing multi-ounce intercept, at open-pittable thicknesses and depths, 2.5 kilometers from our San Albino mine, which has been in commercial production for the past 9 months and is one of the highest-grade open pit mines globally. These results at LC-S bode well for our maiden resource at Las Conchitas, expected late this year."

About Las Conchitas

The Las Conchitas area covers approximately 3.75km² and is situated immediately to the south of San Albino, where the Company is currently operating a 500 tonne per day ("tpd") mining and milling operation (see attached drill plan), and immediately to the north of the historical El Golfo Mine located within the Company's El Jicaro Concession.

Las Conchitas contains numerous mineralized structures over a 1,700m by 800m area and it has been subdivided into three primary areas: Las Conchitas north ("LC-North"), Las Conchitas central ("LC-Central") and LC-S. Each of these areas are comprised of multiple subparallel, northeast-southwest striking and gently dipping mineralized veins. The Company's main focus was LC-S; where over the last 10 years drilling campaigns at Las Conchitas completed 388 drill holes, totaling 35,254m. 

The mineralized zones, consisting of multiple parallel quartz veins, are trending in a northeast-southwest direction, and shallowly dip to the northwest, following the topography. Recent drilling and geological modeling demonstrate that the LC-S mineralized area has continuity over approximately 430m along strike by 700m down dip. Results from previously released hole LC20-323 which intersected 7.39 g/t Au and 23.6 g/t Ag over 3.00m (2.5 ETW) (see August 18, 2021 press release) indicate that this zone may extend another 420m to the northeast demonstrating at least 850m strike potential. Additional drilling is planned to test the continuity of the zone to the northeast.

Table: Assay Results Reported in This Press Release

The mineralized intervals shown above utilize a 1.0 g/t gold cut-off grade with not more than 1.2m of internal dilution. *Widths are reported as drill core lengths. **Indicates use of metallic screening method for assays. ***Estimated True Width is estimated from interpreted sections. In addition to the drill holes presented in the table above, the following drill holes returned only anomalous values: LC21-406, LC21-408, LC21-410, LC21-411, LC21-413, LC21-414, LC21-417, LC21-418, LC21-420, LC21-422, LC21-424 to LC21-428, LC22-439 and LC22-440   In addition to the drill holes presented in the table above, the following drill hole returned no significant values: LC21-409.

Sampling, Assaying, QA/QC and Data Verification

Drill core was continuously sampled from inception to termination of the entire 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. In order to test for the potential presence of coarse gold in certain samples, 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.
