Drilling at Las Conchitas Extends Near Surface, High-Grade Gold Mineralization Across Multiple Intercepts at the Bayacun Zone, Highlighted by 84.64 g/t Gold Over 1.6 Meters






Mako Mining Corp. (TSX-V: MKO) (OTCQB: MAKOF) is pleased to report positive drill results from 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 in order to delineate a maiden resource estimate.  Since 2019, the Company has completed 148 shallow drill holes totaling 11,450.1 meters within the Las Conchitas area. 


This press release includes six holes with assay results from the Bayacun Zone (see attached map).  All six holes intersected gold-bearing structures at the predicted locations, confirming both lateral and vertical continuity.  Importantly, five of the six holes intersected gold grades in excess of 23 g/t Au as highlighted below (ranked by grade x thickness). 


  • LC20-181: 84.64 g/t Au and 80.2 g/t Ag over 1.60 m, 80 m from surface
  • LC20-183: 25.78 g/t Au and 18.3 g/t Ag over 3.85 m, 45 m from surface
  • LC20-182: 24.85 g/t Au and 18.0 g/t Ag over 2.10 m, 107.5 m from surface
  • LC20-164: 23.57 g/t Au and 20.5 g/t Ag over 1.20 m, 35 m from surface
  • LC20-163: 37.90 g/t Au and 14.8 g/t Ag over 0.50 m, 55.5 m from surface


The highest grade interval reported in this press release comes from hole LC20-181, which was designed to test the strike extension of the Bayacun Zone encountered in previous drilling.  Specifically, LC20-181 intersected the Bayacun Zone 35 m northeast of hole LC20-162, which returned 30.61 g/t Au and 37.1 g/t Ag over 3.4 m (see attached cross section and press release dated March 11, 2020).


From the same drill pad, vertical drill hole LC20-182 intersected 24.85 g/t Au and 18.0 g/t Ag over 2.10 m and extended the down-dip length of mineralization from a surface exposure down to 140 m (see attached cross section).


Results to date from the Bayacun Zone indicate approximate dimensions of 70 m along strike by 110 m down dip and continues to be open along strike and at depth.


Akiba Leisman, Chief Executive Officer of Mako states, “every hole referenced in this press release hit significant gold mineralization with grades as high as 84.6 g/t Au over 1.6 m.  The Bayacun Zone of the Las Conchitas area is proving to be a predictable and high-grade target at relatively shallow depths.  Even though precautions are being taken across our Nicaraguan operations to reduce the threat of COVID-19, a drill rig will continue to focus on exploration drilling at Las Conchitas with the goal of delineating a maiden resource next calendar year.”


The thickest intercept was encountered in hole LC20-183, which intersected 25.78 g/t Au and 18.3 g/t Ag over 3.85 m, approximately 45 m from surface.  LC20-183 was designed to test the strike extension from holes LC20-181 and 182 for an additional 60 m and the down-dip extension of the mineralized zone intersected by holes LC19-104 and LC19-105, which returned 42.79 g/t Au and 59.9 g/t Ag over 1.70 m and 19.34 g/t Au and 13.6 g/t Ag over 4.90 m, respectively (see press release dated September 10, 2019).


Additionally, LC20-183 intersected a highly mineralized zone approximately 95 m down-dip from an exploration pit at the Rosibel Zone, where a shallow-dipping quartz vein was exposed.  Vertical sampling of the zone in the pit returned 29.30 g/t Au and 44.7 g/t Ag over 1.5 m.


This press release contains results from six holes totaling 537 m drilled into the Bayacun Zone.  There are 19 additional drill holes still awaiting assay results from the Bayacun Zone.

The mineralized intervals shown above utilize a 1.0 g/t gold cut-off grade with not more than 1.0 meter of internal dilution. *Lengths are reported as core lengths. True widths vary depending on drill hole dip, the veins are shallow dipping and typical true widths are 80-100% of the downhole width.



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.
