Mako Mining Corp. Announces Discovery of New Gold Bearing Veins at Las Conchitas North
Intersects 51.80 g/t of Au and 29.8 g/t of Ag over 0.90 m (Estimated True Width)VANCOUVER, June 1, 2022 - Mako Mining Corp. (TSXV: MKO) (OTCQX: MAKOF) ("Mako" or the "Company") is pleased to report positive drill results from the San Pablo zone at the Las Conchitas-North ("LC-N") area of its wholly-owned San Albino-Murra property. The LC-N area is located approximately 750 meters ("m") south of the San Albino gold mine ("San Albino") which is currently in commercial production.
Initial drilling in 2018 targeted a mineralized structure exposed in the historic San Pablo working where seven drill holes, totaling 260 m were drilled. No additional drilling had been completed in the area until this year, which has resulted in the discovery of two new veins, the Mina Francisco and the Tirado vein.
Highlights of the recent drilling
- Mina Francisco ("MF")
- 51.80 g/t Au and 29.8 g/t Ag over 0.90 m (ETW)
- San Pablo ("SP")
- 27.60 g/t of Au and 17.1 g/t of Ag over 0.50 m (ETW)
- Tirado ("TD")
- 39.30 g/t Au and 49.0 g/t Ag over 0.50m (0.4 m ETW)
- Tirado
- 10.97 g/t Au and 23.2 g/t Ag over 3.50 m (3.30m ETW)
| Note * ETW are estimated true width measured from interpreted sections |
Akiba Leisman, CEO of Mako states, "the discovery of the Mina Francisco and Tirado veins are the first results back from our recently announced $17.2 million exploration program, which is being funded through cash flow from the San Albino mine 750 meters to the north. Mina Francisco has already been extended to 200 meters of strike and nearly 330 meters of dip, beginning from surface, open in all directions, with grades and thicknesses very similar to that of San Albino. These results have great potential to yield additional open-pittable mineral resources. Now that we have seven core rigs at site, further exploration results are expected to be delivered throughout the year, with the goal of making additional discoveries."
To date, a total of 4,670 meters in the 2022 drilling campaign have been completed in 35 drill holes at Las Conchitas North resulting in the discovery of the Mina Francisco and Tirado veins as well as further delineation of the San Pablo vein (see attached drill plan and table below). The three mineralized structures are located at the northern portion of the Las Conchitas area in Nueva Segovia, Nicaragua which is interpreted to be the southwest portion of a new emerging orogenic gold camp with over 28 kilometers of relatively unexplored strike length.
Past drilling had returned good indications of San Pablo gold mineralization, but the recent drilling below the known mineralization represents a significant, new discovery of the Mina Francisco vein in the area. An initial drill program consisting of 26 scouting exploration holes were designed to test a large geochemical soil anomaly (500m x 250m), targeting the portion of the zone where no previous drilling had been completed.
The discovery drill hole, LC22-515, collared below the known mineralization at San Pablo, intersected an interval of 12.72 g/t Au and 8.6 g/t Ag over 1.70 m (1.50 m ETW), starting at vertical depth of 151 m (see attached cross section). This hole confirmed the presence of the Mina Francisco vein in the area approximately 270 m down dip of a surface expression of the vein (historical Mina Francisco Tunnel), across a ravine previously interpreted to be a fault boundary.
The vein was intersected approximately 36 m up-dip and 34 m along strike of the mineralization indicated by the discovery hole, resulting in the high grade intersect of 26.50 g/t Au and 34.2 g/t Ag over 0.60 m (0.50m ETW) in hole LC22-517, at vertical depth of 119 m.
An additional five separate mineralized intervals were intersected in hole LC22-524, approximately 233 m up-dip from the discovery hole, including thus far the highest gold values in the Mina Francisco vein of 51.80 g/t Au and 29.8 g/t of Ag over 0.90 m (ETW), starting at vertical depth of 47.2 m, and corroborating continuity along dip.
To date, the Mina Francisco vein has been intersected in at least 14 of the 19 holes targeting the vein with an average thickness of approximately 1.3 m, which is similar to the average width of the San Albino vein currently being mined to the north. Four drill holes that did not intersect a discernable vein, did intersect fault gouge containing quartz breccia (assays pending). At present, the Mina Francisco vein has been intersected over a strike length of approximately 200 m and 328 m down dip. The Mina Francisco vein remains open along strike and down dip. Results are pending for 14 holes which targeted the Mina Francisco vein.
Fifteen drill holes targeted the San Pablo and Tirado zones, which lie above the Mina Francisco zone. The initial drilling program at the San Pablo zone in 2018 consisted of seven diamond drill holes, six vertical drill holes and a single angle hole. All drill holes intersected the mineralized zone at approximately 30 m vertical depth. The best drill result of 6.0 m averaging 4.13 g/t Au and 3.8 g/t Ag was reported in hole SP18-03. The same year, the Tirado zone was exposed in a single trench situated approximately 100 meters west of the San Pablo zone (see press release dated November 28, 2018). Trench SAM18-TR-31 exposed a vein structure parallel to San Pablo where the sampling returned 1.0 m of 37.60 g/t Au and 98.1 g/t Ag (vertical sample).
The best TD/SP results were returned in drill hole LC22-502 which intersected both zones. The first zone,TD, containing a highly weathered quartz vein, intersected 12.60 g/t of Au and 95.1 g/t of Ag over 0.60 m at vertical depth of 69.2 m. The second zone, SP, intersected at the vertical depth of 93.7 m an interval grading 27.60 g/t of Au and 17.1 g/t of Ag over 0.50 m (ETW).
LC22-506 also intersected the TD and SP zones and confirmed mineralization for an additional 151 m and 162 m up-dip, respectively. This drill hole intersected an interval of 39.30 g/t of Au and 49.0 g/t of Ag over 0.50 m (ETW), 23.5m from surface and 17.50 g/t of Au and 17.0 g/t of Ag over 0.70 m (ETW), at vertical depth of 47.50 m which appears to be a splay of the TD vein. An interval grading 8.76 g/t of Au and 9.0 g/t of Ag over 0.90 m (ETW), at vertical depth of 101 m, has been interpreted as the SP zone.
The current intersects of the TD vein vary in widths from 0.5 m to 3.3 m, and are considered to be an important part of a larger vein system, including the San Pablo and Mina Francisco veins, which have excellent potential for open pittable gold mineralization, very similar to San Albino.
The Company has completed nine condemnation drill holes totaling 1,402 m within the proposed waste dump area. Gold mineralization was intersected in three drill holes with the best results in hole CNB22-01 of 10.97 g/t of Au and 23.2 g/t of Ag over 3.50 m (3.30m ETW). The condemnation holes intersected the TD vein below open pit depths and do not affect the location of the proposed waste dump; however, they indicate the potential for mineralization that could be accessed from underground.
In 2022, the Company intends to complete environmental, metallurgical and engineering studies, and to initiate the mine permitting process for Las Conchitas. A maiden resource estimate for the entire Las Conchitas area is planned for Q4 2022 - Q1 2023.

In addition to the drill holes presented in the table above, the following drill holes returned only anomalous values: CNB22-04, CNB22-07, LC22-509, LC22-510 and LC22-514. In addition to the drill holes presented in the table above, the following condemnation drill holes returned no significant values: CNB22-05, CNB22-06, CNB22-08 and CNB22-09. |
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 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.
