Aris Gold announces drill results at the Marmato Deep Zone, including 78.1 metres at 3.43 g/t Au (true width 30.8 m)






Aris Gold Corporation  (TSX: ARIS) (OTCQX: ALLXF) announces high-grade gold intercepts over broad widths at the Marmato mine in Colombia.


The 2020-2021 drill program that began in May 2020 at Marmato comprises 60 holes totalling 35,000 metres and is now approximately 50% complete. Drilling to date has demonstrated high-grade mineralization over broad widths, demonstrating potential to extend the 13-year mine life outlined in the Company’s Pre-Feasibility Study dated September 18, 2020 with an effective date of March 17, 2020.


The principal objective of the drill campaign is to convert Inferred Mineral Resources to Indicated Mineral Resources. In addition to the Deep Zone, the campaign is also testing the newly discovered Fortaleza Zones A and B to the north, which opens up a new area that will require further drilling to evaluate its potential.


Aris Gold CEO Neil Woodyer commented, “Our ongoing drill program at Marmato continues to deliver on our objective of adding to the already large gold inventory and 13-year mine life. Drilling in the Deep Zone is demonstrating potential for a larger, higher-grade system than previously envisioned. In addition, drilling on the newly discovered Fortaleza zones to the north confirms a prospective new area worthy of additional testing.”




The table below lists new intercepts greater than 1.0 g/t gold received since the Caldas Gold news release of November 24, 2020. Results reported here include six drill holes totalling 4,069 metres.

* Denotes underground drill holes drilled at -50 to -73 degrees from the horizontal. The intersection widths do not represent true widths. The true widths estimated from the geological model are also given. Sample lengths average 1.60 metres but may be varied for geological and recovery factors. Intersections were calculated using a cut-off grade of 0.5 g/t gold, and no more than 5.0 m of continuous internal dilution for intervals up to 50 m, no more than 10 m of continuous internal dilution for intervals of 50-200 m, and no more than 20 m of continuous internal dilution for intervals greater than 201 m. Gold grades were capped at 13.0 g/t gold which affects 14 samples of a total of 2014 samples. Intervals greater than or equal to 1.0 g/t are reported.
** Denotes directional drilling mother and kick-off holes. The directional drilling kick-off holes were drilled at -48 and -45 degrees from the horizontal. The collar coordinates are for the kick-off point in the mother hole.
The holes were drilled from three purpose-built underground drill stations on levels 20 and 21 of the mine.
The datum used for the collar coordinates is the official Colombian Magna Sirgas system. “masl”: metres above mean sea level.



Drill collar location, elevation, azimuth and dip are as follows:


Hole Easting Northing Elevation (masl) Azimuth Inclination Length  (m)
MT-IU-075 1163641 1097817 997.09 231 -67 650.65

The ongoing 2020-2021 drilling campaign has been successful in showing higher-grade mineralization over broad widths in the Main Zone (MZ) below the 500-metre level and in the New Zone above the 500-metre level, which strengthens the probability of adding a significant amount of mineral resources to the current inventory. The higher-grade shell is defined as greater than 2.5 g/t Au and lies within the grade shell of 1.7 g/t Au used to build the geological model of the Deep Zone.


Infill drilling in the MZ has extended the higher-grade mineralization over broad widths down to the 400-metre level, well below the 500-metre level that is the bottom of the Indicated Mineral Resource, and remains open at depth. Drill holes MT-IU-75 and MT-IU-078 confirm that the MZ is branching into three separate bodies (A, B, C) to the southeast with the three reporting higher-grade mineralization over broad widths. Drill hole MT-IU-075 intersected 39.75 m at 2.35 g/t Au in the Main Zone A, 21.84 m at 2.07 g/t Au and 19.90 m at 1.94 g/t Au in the Main Zone B, and 13.17 m at 3.35 g/t Au in the Main Zone C. Drill hole MT-IU-078 intersected 26.45 m at 2.83 g/t Au in the Main Zone A, 36.20 m at 3.68 g/t Au in the Main Zone B, and 51.40 m at 2.46 g/t Au in the Main Zone C.


Two wildcat drill holes, MT-IU-077 and MT-IU-079, were successful in intersecting higher-grade zones over broader widths compared to previous drilling in the Fortaleza Zones A and B, which opens a new area that requires further drilling to fully evaluate its potential. Drill hole MT-IU-077 intersected 35.65 m at 2.82 g/t Au and 76.65 m at 1.93 g/t Au in Fortaleza Zones A and B, including two vein-related intercepts that returned 10.90 m at 3.61 g/t Au and 11.85 m at 2.93 g/t Au, respectively, in the Fortaleza Zone B. Drill hole MT-IU-079 intersected 52.40 m at 1.67 g/t Au and 18.90 m at 2.37 g/t Au in Fortaleza Zones A and B.


Infill drilling in the NZ confirms higher-grade mineralization over broad widths above the 500-metre level, which is the bottom of the Indicated Mineral Resource. Kick-off drill hole MT-MH01-01 intersected 361.45 m at 2.21 g/t Au, including 78.10 m at 3.43 g/t Au in the NZ, and 79.85 m at 3.07 g/t Au in the MZ. Kick-off drill hole MT-MH02-01 intersected 41.10 m at 2.57 g/t Au in the NZ, and 172.80 m at 1.95 g/t Au in the MZ, including 45.50 m at 2.33 g/t Au and 94.70 m at 2.13 g/t Au.


The style of mineralization for the intersections associated with the NZ and the Fortaleza Zone is the same as the MZ and is characterized by very narrow veinlets of quartz-pyrrhotite-bismuth tellurides-free gold with minor amounts of pyrite and chalcopyrite, rimmed by a narrow halo of sodic-calcic alteration. The two high-grade intersections in MT-IU-077 in the Fortaleza Zone are associated with thick quartz veins, which is a different style of mineralization that requires further investigation.


Most of the drill holes of this phase of drilling end within the low-grade shell with the result that the MZ is open on the southwest side. This is due to the location of underground drill stations above and close to the steeply plunging low grade shell. However, the holes achieved their objective of fully cutting the high grade MZ.
