Mako Mining Intersects 33.91g/t Gold over 1.7m Estimated True Width (ETW) at Las Conchitas Central, 12.73 g/t Au over 4.2m ETW at Las Conchitas South and Multiple High Grade Silver Intercepts up to 3,792.0 g/t Silver over 1.0m across Las Conchitas

 

 

 

 

 

Mako Mining Corp. (TSX-V: MKO) (OTCQX: MAKOF) has received additional high-grade results from its recent definition and expansion drilling program at the Las Conchitas area on its wholly owned San Albino-Murra property. The Las Conchitas area is located immediately south of the San Albino Mine which is currently in commercial production. The geology at Las Conchitas is very similar to San Albino consisting of gently dipping, stacked, 1-3 meter (m) wide, high grade gold quartz veins interpreted to be part of a larger orogenic system.

 

At the Las Conchitas area, which is located between the San Albino Mine and the historical El Golfo Mine on the Company’s El Jicaro Concession, the Company has completed 718 drill holes to-date totaling 78,641m, of which 51% were drilled in 2022. Las Conchitas comprises an area of approximately 3.75 km2 and is subdivided into three primary areas: Las Conchitas North (“LC-N”), Las Conchitas Central (“LC-C”) and Las Conchitas South (“LC-S”). The objective of the drilling at the Las Conchitas area is to test the strike and dip extension of gold mineralization amenable to both open pit and underground mining methods, and to provide sufficient information for a mineral resource estimate.

 

Highlights of the recent drilling at Las Conchitas:

 

Las Conchitas – North

  • Mina Francisco
    • 16.56 g/t Au and 38.8 g/t Ag over 1.80m Estimated True Width
    • 24.10 g/t Au and 44.8 g/t Ag over 0.90m (0.8m ETW)
  • Crucita
    • 22.60 g/t Au and 21.4 g/t Ag over 0.70m (0.6m ETW)

Akiba Leisman, CEO of Mako states that “Las Conchitas continues to yield high grade, near surface intercepts across LC-N, LC-C and LC-S. Additionally, we intersected a completely different style of mineralization, containing high grade silver across all areas of Las Conchitas, with grades up to 3,792 g/t Ag over 1.0m.  We will continue to investigate the significance of these silver results, which may have a positive impact on the economics of the mine.”

 

Las Conchitas – North

 

In 2022, the Company completed an aggressive drilling campaign within the LC-N area, resulting in the new discoveries of the Mina Francisco and Crucita zones (see press releases dated June 1, 2022 and July 28, 2022).  To date, a total of 27,295m in the 2022 drilling campaign have been completed in 202 drill holes at the LC-N area.

 

Drill hole LC22-560 intersected an interval of 16.56 g/t Au and 38.8 g/t Ag over 1.80m (ETW), 22m from the surface (see attached drill plan and table below). This intercept represents a 38m strike extension south of the high-grade interval 20.30 g/t Au and 55.8 g/t Ag over 2.00m (1.9m ETW), 5m from surface, intersected by drill hole LC22-558 (see press release October 24, 2022).

 

LC22-739 intersected multiple mineralized zones (see Table 1 below), including 24.10 g/t Au and 44.8 g/t Ag over 0.90m (0.8m ETW), at vertical depth of 124.3m. This interval extends the Mina Francisco mineralization 46m down dip from drill hole LC22-517 which intersected 26.50 g/t Au and 34.2 g/t Ag over 0.60m (0.5m ETW).

 

Drilling in the Intermediate zone intersected 22.60 g/t Au and 21.4 g/t Ag over 0.70m (0.6m ETW), in hole LC22-919, at a vertical distance from surface of 91.8m. This interval is interpreted as the Crucita vein which projects 103.5m up dip to surface where a historical tunnel is located.

 

Las Conchitas – Central

 

At LC-C, drill hole LC22-825 intersected a 2.00m (1.9m ETW) interval of 33.91 g/t Au and 30.0 g/t Ag.  This interval, 115m vertically from surface, confirmed an 89.0m down dip extension of a 7.20m wide mineralized interval (6.7m ETW), of 15.36 g/t Au and 16.0 g/t Ag, 69.2m below surface, in drill hole LC22-818 (see press release on September 08, 2022).

 

Las Conchitas – South

 

LC-S is the most advanced area in terms of drilling, where 416 drill holes, totaling 38,739m, have been completed. This area is comprised of four principal mineralized zones. The recent drilling by the Company focused on three of these zones: Bayacun, El Limon and Mango.

 

Drill hole LC22-490, designed to test the extension of the Bayacun zone, intersected a 6.00m wide interval (4.2m ETW), grading 12.73 g/t Au and 24.7 g/t Ag, including 18.50 g/t Au and 32.5 g/t Ag over 3.00m (2.1m ETW) at 37.5m below surface (see cross section). This mineralized interval represents a 26.8m west-southwest strike extension of drill hole LC20-216, which graded 21.00 g/t Au and 28.3 g/t Ag over 1.20m, (see press release on June 20, 2020).

 

Note: The mineralized intervals shown above utilize a 1.0 g/t gold cut-off grade with not more than 1.0 m of internal dilution. *Previously reported intervals.**Widths are reported as drill core lengths.***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: LC22-557, LC22-559, LC22-562, LC22-567, LC22-569, LC22-571 to LC22-573,LC22-577, LC22-731 to LC22-732, LC22-745 to LC22-748, LC22-923 to LC22-924, LC22-926, LC22-837 to LC22-838,  LC22-476, LC22-480 to LC22-481, LC22-483 and LC22-487. In addition to the drill holes presented in the table above, the following drill holes returned no significant values: LC22-482 and LC22-489.

 

 

High Grade Silver

 

In addition to the typical vein hosted gold/silver zones discussed above, 32 drill holes at Las Conchitas (see Table 2 and drill plan below) intersected a completely different style of mineralization, characterized by high grade silver and relatively no gold. This style of mineralization is typically associated with 1-3m wide broken/fractured zones often at similar depths below surface, with no clear association with quartz veining or alteration. The geochemistry of these zones consists of high silver assays (see Table 2 below), anomalous tungsten (W >100 ppm) and elevated nickel and copper grades, associated with potassium and aluminum anomalies. Additional geologic investigations are underway to determine the nature and economic significance of these zones.

 

Drill hole LC21-419 positively tested and confirmed the typical gold/silver mineralization of the Mango zone (LC-S). 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 (see press release on March 17, 2022).  The same drill hole intersected an interval, 123m below surface, of 3,792 g/t Ag over 1.0m.  Besides being the highest individual silver value reported at Las Conchitas, this interval contains high copper (Cu >10,000ppm or >1%) and nickel (1,268ppm) grades. The same type of mineralization was intersected by drill hole LC21-408, which reports 2,418.0 g/t Ag, located approximately 122m to the south.

 

The same style of mineralization was intersected by several drill holes close to the surface (see Table 2 and drill plan), including drill hole LC19-94 which intersected a 3m wide interval grading 1,214.5 g/t Ag, 28.5m below surface.

 

In total, 34 drill holes intersected the same style of mineralization above an internal cutoff grade (80.0 g/t Ag), including 14 drill holes collared at Las Conchitas North.

 

*Intervals are reported as core lengths

 

 

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 with a minimum sample width of 50 cm. 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 and 100 g/t silver 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 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.
