Rock chip channel sample at La Gloria mine includes 20.76 g/t gold, 15 g/t silver, 0.54% copper across 0.72 m.
Vancouver, British Columbia – September 7, 2021 – Brigadier Gold Limited (the “Company” or “Brigadier”) (TSXV: BRG|FSE: B7LM|USA: BGADF) is pleased to announce further analytical results from additional trenches across the Colinas copper-silver discovery as well as results from the historic La Gloria Gold Mine at its Picachos gold-silver-copper project Sinaloa, Mexico (the “Picachos Project”, “Picachos” or the “Property”).
At Colinas, Trench BRG-50651 was collared 56 metres east-northeast of BRG-50250 (results in press release dated Aug. 4, 2021) and excavated by hand to the northwest for 81 metres. The principal result of BRG-50651 is 0.35% copper and 9 g/t silver across 30 metres between 51 and 81 metres. The anomaly is open to the northwest as shown on the map below. A further 112 metres to the northwest, BRG-50823 returned a result of 60 g/t silver, 0.11% copper and 0.21% lead across 5 m. This includes a result of 257 g/t silver, 0.21% copper and 0.45% Pb across 1 m between 4 and 5 m. Forty-five metres southwest of BRG-50250, BRG-50735 was excavated to the northwest for 113 metres. This trench is on the northwest bank of the arroyo El Habal and bedrock was partially discovered in between deep overburden. From here, an anomaly of 0.11% copper and 5 g/t silver was measured across 54 metres between 18 and 72 metres. At the end of the trench between 110 and 111 metres, one sample returned 1.43 g/t gold, 135 g/t Ag, 0.06% copper, 0.32% lead, 36 ppm molybdenum, 0.17% bismuth, 41 ppm tungsten and 74 ppm tin. This result is notable as it indicates that gold is present in the porphyry environment in sericitic alteration assemblages as well as in veins and stockwork deposits in propylitic and argillic altered volcanic rocks at higher elevations in the southeastern part of the Property.
Rob Birmingham, CEO, comments, “The exploration team led by veteran geologist Michelle Robinson continue to expand on previous successes at the Picachos Project. We’re pleased to see the precious metals rich, copper discovery announced on August 4th is growing in scale and providing the company with exceptional targets for further inspection. Furthermore, we are excited with the discovery of high grade gold, silver and copper in rock chip channel samples at the historic La Gloria mine. We look forward to providing shareholders with continued assays from these new discovery areas as they are received.”

La Gloria Gold Mine is located 4.2 kilometres southeast of Colinas at 950 metres elevation. Mine access is an easterly trending adit 106 metres long that intercepts a honeycomb stope approximately 100 metres long and 1.5 metres wide that trends northwesterly. Sixteen rock-chip channel sample lines were cut across pillars in the stope. The best overall result was 20.76 g/t gold, 15 g/t silver, 0.54% copper, 0.57% Pb and 1.70% Zn across 0.72 m from BRG-50017. This includes 0.12 m of 123.56 g/t Au, 50 g/t Ag, 2.8% copper, 1.35% Pb and 8.00% Zn.

Southwest of La Gloria, 230 linear metres of rock exposed by the bulldozer were sampled at one-metre intervals in eight individual trenches. In this area there are numerous prospect pits and shallow workings for gold hosted in pyroclastic rocks intercalated with intermediate volcanic flows. The most significant result is 25 metres of 0.53 g/t Au, 0.34% Pb and 0.57% Zn in BRG-121950 between 18 and 43 metres. This includes 2 metres of 3.05 g/t Au, 8 g/t Ag, 0.09% Cu, 0.60% Pb and 0.81% Zn between 41 and 43 metres.
Approximately 215 metres NW of La Gloria, exploration of historic soil sample MTA-50409 with values of 1.15 ppm Au resulted in discovery of the Ranas Vein. The best result from 7 cuts across Ranas is BRG-29957 with values of 6.63 g/t Au, 11 g/t Ag and 0.36% Zn across 1.7 metres.
Mechanized trench BRG-50601 was cut across La Cocolmeca Vein 330 metres north of La Gloria. An overall result of 0.39 g/t Au, 7 g/t Ag, 0.09% Cu, 0.08% Pb and 0.29% Zn was returned across 17 metres between 48 and 65 metres. Most of the gold is between 63 and 64 metres with values of 4.36 g/t Au, 6 g/t Ag, 0.09% Cu, 0.15% Pb, 0.47% Zn and 14 ppm W across 1 m.
Eighty metres northwest of La Gloria, Brigadier trenched 47 linear metres under historic soil samples MTA-50413 and 50414 with values of 1.13 and 1.53 ppm gold, respectively. Trench BRG-50501 has an overall result of 0.62 g/t Au, 2 g/t Ag, 0.12% Pb and 0.24% Zn between zero and 35 metres and exposed a geological contact between a glassy quartz porphyritic rhyolite flow-dome (0-22 m) and intermediate pyroclastic country rocks (22-47 metres). The glassy rhyolite is cut by hairline microcrystalline veinlets of quartz with epidote. Gold values in this stockwork/disseminated mineralization range from 0.2 to 0.64 ppm between the interval 0-13 metres, with an average value of 0.35 g/t Au across the first 13 metres. Between 13 and 22 metres, the western contact of the flow-dome contains 1.26 g/t gold across 9 metres with a maximum value of 3.57 g/t Au across 1 m (18-19 m). This type of rhyolite-hosted disseminated/stockwork gold with low base metal values has only been recently documented on the Property at a different flow dome near Santa Elena, 1.4 kilometres northeast of this prospect. This flow-dome has surface dimensions of approximately 250 metres by 350 metres merits further exploration as a disseminated/stockwork gold deposit.
