Mako Mining Corp. (TSX-V: MKO) (OTCQX: MAKOF) is pleased to report positive drill results from infill drilling at the Arras Zone within its San Albino gold project in northern Nicaragua.
The objective of the drill program at the Arras Zone is to increase the level of confidence in the currently defined resources and to define additional, shallow, high-grade resources.
The Company is following a systematic approach of drilling shallow holes by spacing them approximately every 10 meters along strike and every 10-15 m down dip. During 2021, over 2,645 m have been drilled at the Arras Zone in 65 diamond drill holes.
The Arras Zone is located approximately 170 m to the east of the San Albino West Pit, which is currently being mined by the Company. Mineral resources in the Arras Zone account for only 10.9% of the total Measured and Indicated and 26.5% of the Inferred mineral resources estimated by Mine Development Associates, a division of RESPEC, out of Reno, Nevada. A technical report for the updated mineral resource estimate was filed in accordance with National Instrument 43-101, Standards of Disclosure for Mineral Projects under the Company’s SEDAR profile at www.sedar.com and available on the Company’s website at www.makominingcorp.com (see press release dated October 19, 2020).
Akiba Leisman, Chief Executive Officer of Mako states that, “we are continuing to systematically drill the Arras Zone, which we plan to begin mining next calendar year. The Arras Zone is more complex than the nearby San Albino Zone currently being mined, but despite the complexity, it is yielding positive surprises. For example, the shallow intercept of 24.02 g/t gold over 4.4 meters true width in hole AR21-284, which lies outside the current MDA Resource and is open down dip where limited drilling has been completed. We expect this infill program to have a positive impact on the size of the Central Pit which encompasses the Arras Zone.”
Specific comments on significant results reported in this press release are as follows:
The infill-drilling results continue to demonstrate structural continuity and the resource expansion potential of the Arras Zone which has now been measured over a strike length of approximately 380 m and approximately 700 m down dip (see attached drill plan). Continuity of individual areas along strike and down dip varies between 30-50 meters. The Arras Zone remains open down dip.
Drill hole AR21-284, at 14.5 m vertical depth (see attached cross section) intersected 24.02 g/t Au and 29.5 g/t Ag over 5.10 m (4.4 m estimated true width). An interpretation of the drill results indicates that the Arras Zone is affected by subvertical faults, as well as low angle thrust faults. Locally, the low angle faults appear to offset the vein in a manner that produces thickening or duplication of the mineralized zone. The results of hole AR21-284 also confirmed the lateral and down dip continuity of the modeled vein domain. This interval was located below the resource pit shell of the MDA Resource.
Several drill holes intersected multiple mineralized intervals. Drill hole AR21-295, intersected two mineralized intervals. The first was at 20 m below surface with assays of 13.22 g/t Au and 23.0 g/t Ag over 1.50 m (1.1 m estimated true width) and the second interval was approximately 5 m below the first with assays of 2.59 g/t Au and 21.9 g/t Ag over 0.80 m (0.3 m estimated true width).
AR21-319 intersected two mineralized intervals separated by 2.3 m of anomalous material. The first interval was at 24.3 m below surface with assays of 9.99 g/t Au and 10.8 g/t Ag over 2.70 m (2.5 m true width). The second interval was at 29.3 m below surface and assayed 16.71 g/t Au and 19.4 g/t Ag over 2.40 m (1.8 m true width).
AR21-253 intersected a mineralized interval 3.4 m below surface that assayed at 15.27 g/t Au and 19.5 g/t Ag over 3.30 m (3.0 m estimated true width). At 14 m below surface, a second interval assayed at 7.18 g/t Au and 16.0 g/t Ag over 1.20 m (1.1 m estimated true width). The mineralized intervals are located directly below historical dump material which assayed 3.38 g/t Au and 9.1 g/t Ag over 3.4 m.
Historical dump material has been mapped through trenching and drilling over approximately 365 m, generally following a local valley (see attached drill plan). Drilling indicates the historical dump can extend up to 7.0 m in depth with an average width of 1.5 m. Often this material contains remnants of a mineralized vein. Assay results of 108 channel samples from 13 exploration pits in the historical dump material reported a weighted average of 1.78 g/t Au and 4.2 g/t Ag with the highest values of 20.40 g/t Au and 17.3 g/t Ag over 1.0 m. Assay results from drilling of the historical dump material are shown in the table below.
While the Arras Zone has had historical mining, drilling has confirmed that most of the historical mining activities were limited to superficial workings which partially explains the sporadic continuity in the shallow drill holes. Many drill holes intersected the remnants of the vein and confirmed that the vein is only partially removed. AR21-311 intersected a 2 m wide historical working with a portion of the preserved mineralized vein, which assayed at 19.70 g/t Au and 16.3 g/t Ag over 1.00 m (0.9 m estimated true width) above the void and 2.44 g/t Au and 4.1 g/t Ag over 3.00 m (2.3 m estimated true width) below the void.

Arras Zone History
One of the first documented gold discoveries in Central America was in the Arras Zone where gold was mined by the Spanish. According to the “Report on San Albino Gold Mines Situated in Nueva Segovia, Nicaragua” by Rodgers Peale, San Francisco, California date January 12, 1948 “the vein was flat and dipped with the surface of the hill so that it was mined as an open pit by the Spaniards.” It is believed that the gold from the Arras Zone was transported to Ciudad Antigua approximately 21 km to the southwest. Ciudad Antigua was one of the few inland cities raided by pirates, in 1654 it was attacked by one of the most infamous English pirates of the time, the notorious Henry Morgan.
A review of a 1948 report by Rodgers Peale indicates that the Arras Zone was one of the last areas mined at San Albino. The area is described as being historically mined 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, a dip of 60 m and an average width of 1.6 m. Subvertical and low angle faults are described to have offset the veins.
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. Trench and surface channel samples followed a similar procedure as drill core sampling. Continuous samples were collected using a diamond saw or rock hammer and chisel. Care was taken to ensure a consistent channel width of 6 cm wide and 5 cm depth. Individual channel samples range from 0.4 meters to 1.0 meters in length. Both drill core and channel 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.
