VANCOUVER, BC / ACCESSWIRE / July 6, 2021 / Brigadier Gold Limited (the “Company” or “Brigadier“) (TSXV:BRG | FSE:B7LM | OTC PINK:BGADF) is pleased to announce further drill results from exploration of newly identified gold targets at its Picachos gold-silver-copper project Sinaloa, Mexico (the “Picachos Project“, “Picachos” or the “Property“).
Brigadier has received analytical results for diamond drill holes DH-BRG-044 to -050 from SGS Laboratory. Principal results are from 47, 48 and 49, a fence of holes drilled across the northwesterly trending El Placer Vein system (see table below).
In the winter of 2021, the Company completed underground sampling of several historic gold mines along the northwest part of El Placer.
Highlights from underground sampling obtained prior to diamond drilling include:
- 31.4 g/t Au, 11 g/t Ag, 0.2% Cu, 0.5% Pb and 2% Zn across 0.3 meters from Tacuachas Underground Level 1030 (BRG-25139)
- 2.14 g/t Au and 0.1% Pb across 8 m from a surface trench across Tacuachas Open Cut (BRG-117146)
- 7.43 g/t Au, 0.15% Pb, 0.23% Zn across 3.2 m from Lentes Underground Level 1024 (historic sample MCA-27431). This result includes 0.15 m of 40.63 g/t Au with 0.2% Pb and 0.2% Zn
- 4.64 g/t Au, 0.1% Pb and 0.1% Zn across 0.9 m from Corallio Underground Level 1035
- 38.88 g/t Au, 22 g/t Ag, 0.4% Cu, 1.7% Pb, 1.5% Zn and 538 ppm W (tungsten) across 0.5 meters in Chivera Underground Level 1177 (BRG-27106)
- 12.79 g/t Au, 8 g/t Ag, 0.1% Cu, 0.9% Pb, 0.9% Zn across 1 m in Los Huaraches Underground Level 1155 (BRG-25131). This includes 0.1 m of 117.45 g/t Au, 57 g/t Ag, 0.2% Cu, 3.2% Pb and 2.6% Zn
Host rocks to the mineralization are mainly rhyolitic ignimbrite. Regionally, these are pervasively silicified and brecciated within the El Placer Vein system. Microcrystalline quartz, epidote and base metal sulfides such as galena and sphalerite occur in the silicified matrix between rock fragments. Gold is concentrated in shear zones marked by argillic alteration with or without quartz veining.
DH-BRG-047 is completely mineralized and returned an overall result of 0.41 g/t Au with 0.2% Zn across 60.3 meters. From the geological model, it appears to have tested a series of shears in the hanging wall to La Botica represented by Tacuachas, Coralillo, Los Lentes and at least two newly defined structures in the footwall to Tacuachas. Notable individual results are 4.03 g/t Au, 4 g/t Ag, 0.2% Pb and 0.1% Zn across 0.5 m, correlated to the Corallio Vein and 1.49 g/t Au with 0.3% Zn across 1.8 m correlated to Los Lentes Vein.
The main results from DH-BRG-048 are in the top of the hole. The interval between 3 and 4 meters contains 6.89 g/t Au with 0.04% Cu, 0.1% Pb and 0.1% Zn and is correlated to the Tacuachas Vein. Between 14 and 18 meters an intercept of 1.85 g/t Au with 0.1% Pb and 0.1% Zn defines a new shear zone in the footwall to Tacuachas with a maximum value of 5.51 g/t Au across 1 m between 16 and 17 m.
DH-BRG-049 tested under Cerro La Chivera and returned an average result of 0.27 g/t Au with 0.01% Cu, 0.1% Pb and 0.2% Zn across the entire length of 123 m. Between 7 and 8 m, values of 2.85 g/t Au, 0.04% Cu, 0.1% Pb and 0.4% Zn correlate to the Tacuachas structure. La Botica, defined underground about 600 meters southeast of this drill hole, strikes through DH-BRG-049 between 40.5 and 56 meters downhole with a peak value of 1.08 g/t Au returned across 4 m between 52 and 56 m. Chivera is correlated to the interval between 77 and 95 meters with peak values of 1.1 g/t Au, 0.4% Pb and 1.7% Zn occur across 4 m between 77 and 81 m and 3.51 g/t Au and 0.1% Pb across 1 m between 92 and 93 m. Finally, Tatemales, historically exploited underground about 300 meters southeast of this drill hole fence, projects through DH-BRG-049 between 98 and 123 m.
Brigadier has cut a 69 meter long surface trench using the D6 along approximately the same line as DH-BRG-047. By using the bull dozer, a more accurate assessment of surface gold mineralization will be attained. This trench was sampled at 1 meter and 0.5 meter intervals using a chisel and hammer to channel across the rock (dry sampling). Results for the machine dug trench are pending.

In Q2 of 2021, Brigadier completed underground and surface trench sampling of La Gloria, El Salvador, El Cobre and Palodismo and made a significant copper-silver discovery in the porphyry area in the northwestern part of the Property. Analytical results are still pending for about 900 samples from these work areas. The laboratory developed a shortage of reagents in the spring and assaying is proceeding at a slower pace than usual. In May, the Company prepared the road to the campsite at La Flauta in the southeastern part of the Property and in June, Brigadier completed a new access road to the northwestern part of the Property, to better support exploration of the porphyry this fall. The Company installed a satellite camp at La Flauta in early June and started hand-trenching across selected locations of the El Placer Vein system within 1.5 km of the camp. Underground mapping and sampling of historic workings in the area is also in-progress. A route to copper-silver rich mineralization at Garabato has been surveyed and construction is in-progress.
Drill hole results for gold, silver, copper, lead and zinc. Not enough is known about the mineralization to reliably estimate true widths. DL = at or near detection limit.
