Infill Drilling at Arras Zone Within San Albino Intersects 30.27 g/t Gold Over 4.2 Meters (Estimated True Width) 2 Meters From Surface

 

 

 

 

 

Mako Mining Corp. (TSX-V: MKO) (OTCQB: MAKOF) is pleased to report positive results from infill drilling at its wholly-owned San Albino gold project located in Nueva Segovia, Nicaragua.

 

To date, 5,491.90 meters of drilling in 134 diamond drill holes has been completed within the Arras Zone, which is the area outlined by the Central and Northeast pits in the Company’s preliminary economic assessment, dated April 29, 2015 and available under the Company’s profile on SEDAR at www.sedar.com, with assays reported for 28 of these holes in this press release (see attached map).

 

The 2019-20 drilling program targeting the Arras Zone was focused on identifying shallow mineralization that can augment the initial phase of mining at the West pit.  The Company followed a systematic approach of drilling shallow holes every 20 m along strike and 20-40 m down dip.  The results indicate a zone of approximately 80 m along strike by 100 m down dip with grades and thickness that are variable within the zone.  Importantly, the Arras Zone remains open down dip with previous wide-spaced drilling intersecting the zone at over 600 m down dip.

 

The highlights of this press release are drill holes AR20-162 and AR20-166.  Both holes were drilled to test mineralization encountered in tunnel AR13-TNL-03, which had a couple of channel samples of vein material that assayed over 30 g/t Au.  Drill hole AR20-162 tested the surface expression of the vein exposed in tunnel AR13-TNL-03 and drill hole AR20-166 tested the same vein along the strike and down dip.

 

AR20-162 intersected 30.27 g/t Au and 31.2 g/t Ag over 5.5 m (4.2 m estimated true width) approximately 2 m from surface (see attached cross section). This hole tested the surface expression of the vein encountered in tunnel AR13-TNL-03.  Results from AR20-162 indicate a similar grade approximately 10 m up dip over a wider interval.

 

AR20-166 was collared approximately 36 m north and down dip from AR20-162 and intersected a zone with an estimated true thickness of 2.7 m approximately 1.5 m from surface.  The mineralized zone encountered in AR20-166 had a total of five significant intercepts although the drill hole had poor recovery and possibly encountered several historic workings.  The two highest grade intercepts were 63.10 g/t Au and 46.4 g/t Ag over 2.15 m and 28.40 g/t Au and 33.3 g/t Ag over 1.0 m (see attached cross section).

 

Three Arras Zone holes from the 2019-20 drilling program were previously released, highlighted by AR19-115, which intersected 24.18 g/t Au and 28.5 g/t Ag over 6.45 m (5.9 m estimated true width) approximately 29 m from surface (see attached longitudinal section and press release dated September 4, 2019).

 

A diamond drill rig along with a production drill rig will continue to identify additional shallow mineralization and to quantify historic dumps along a previously tested ravine between the shallow and deeper portion of the Arras Zone (see attached map).  Results are pending from a total of 103 holes in the Arras Zone.

 

Mako is also pleased to report that mining at the West pit has recommenced after a six-week pause to implement safety protocols due to the COVID-19 global pandemic.  It is anticipated that mining will ramp up over the course of the next few months.

 

Akiba Leisman, Chief Executive Officer of Mako states “it is rare in modern gold mining to intersect more than 30 g/t Au over four meters estimated true width and only a couple of meters from surface.  It is encouraging to see positive results from drilling in the Arras Zone because the zone is not as well advanced as the zones within the West pit, where the bulk of the infill program was focused last year, and where initial mining has recommenced.  Today’s results and those to follow have the potential of improving the already robust San Albino gold project by bringing in high-grade and near surface ounces into the mine plan earlier than anticipated.”

 

History of the Arras Zone

 

Historic data indicates that the Arras Zone was discovered by the Spanish, with mining limited to superficial workings where veins outcropped and formed the southern dip slope; this may partially explain the sporadic continuity in the shallow drill holes.

 

A review of a 1948 report by Roger Peale indicates that the Arras Zone was one of the last areas mined at San Albino.  The area is described as being in production as late as 1943 and with several shoots extending 30 m along strike and 20 m down dip.  Overall, the Arras Zone is described as having a strike extent of 200 m and dip of 60 m and average width of 1.6 m.  Subvertical and low angle faults are described to have offset the veins.

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. * Indicates use of metallic screening method for assays. ** True width is estimated from interpreted sections.

 

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, 30gram 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 used the standard Fire Assay-Gravimetric method unless otherwise indicated as using the metallic screening 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 ratio of 1 control sample per every 10 samples.  Analytical results of control samples confirmed reliability of the assay data.
