Vancouver, British Columbia – March 22, 2021 – Brigadier Gold Limited (the “Company” or “Brigadier”) (TSXV: BRG|FSE: B7LM|USA: BGADF) is pleased to announce the discovery, and systematic sampling of over two dozen historic underground workings at its Picachos gold-silver project, Sinaloa Mexico (the “Picachos Project”, “Picachos” or the “Property”).
Brigadier has rehabilitated, mapped and sampled 29 newly discovered historic mine workings in the central part of the Property near the intersection of the ENE trending Cocolmeca Vein system (CVS) and northwesterly trending El Placer system. The underground workings are concentrated in two areas named El Cobre and El Placer Norte (Figure 1).
Having discovered, accessed and sampled these underground workings was an efficient and inexpensive way to improve the Company’s knowledge of the mineralizing systems at Picachos. The pending assay results together with related surface trenching and nearby diamond drilling will assist in understanding the mineralization on the property and greatly assist in identifying our next drill targets.
“There is a lot of geological action in the Cobre Area”, commented Geologist and Qualified Person, Michelle Robinson. “We have northerly trending veins represented by El Cobre, Las Calzadas and 27047. These appear cross-cut and offset by the northwesterly trending El Herrero Vein. More recent strike-slip movement on La Cocolmeca is regionally important and apparently offsets some vein segments. Further, the intrusive rocks into the volcanic pile contain orbicules, a feature indicative of volatile-rich melts capable of generating robust hydrothermal systems in the porphyry environment. For now, we are exploring the vein potential, but this Project has an exposed porphyry system in the northwest, and buried parts may be discovered by drilling under veins such as El Cobre”.
El Cobre Area
At El Cobre, five principal veins have been identified: (i) El Cobre, (ii) El Herrero, (iii) Las Calzadas, (iv) La Cocolmeca and (v) Vein 27047. The veins are hosted in ignimbrites correlated to the Socavon member of the Late Cretaceous Tarahumara Volcanic Arc. These ignimbrites unconformably overlie submarine andesitic volcanic rocks tentatively assigned to the Jurassic Guerrero Terrane. The strata are intruded by orbicular monzonite porphyry that is younger than the 74-million-year-old Socavon Ignimbrite. Brigadier has assay results for Level 755, a crosscut 10.1 metres long oriented 070° NE across El Herrero Vein (Fig. 2). The first 8 metres intercepted 0.12% copper in a quartz-chalcopyrite-pyrite stockwork hosted in pervasively silicified ignimbrite. The last 2.1 metres intercepted 3.3% copper and 0.56% lead with 108 g/t silver, 0.1 g/t gold, 177 ppm bismuth and 23 ppm tungsten. Most of the assays for El Cobre are pending.
El Placer Norte Area
At least six veins comprise the northern part of the El Placer Vein system (i) Las Tacuachas, (ii) Los Lentes, (iii) Coralillo, (iv) La Chivera, (v) El Huarache y (vi) Pantufla. These veins are hosted in rhyolitic ignimbrite of probable Paleocene age that unconformably overlie the Socavon Ignimbrite. These veins were defined by mapping and sampling historic workings between 1000 and 1180 metres elevation. The historic workings are mainly short adits that follow narrow higher-grade intervals within the larger El Placer Vein system. Individual sample results for Las Tacuachas, Los Lentes and Corallio are in Table 1. The best result from the underground work was 31.4 g/t Au, 11 g/t Ag, 0.2% Cu, 0.5% Pb and 2% Zn across 0.3 m in sample BRG-25139. To better understand the potential of the larger system Brigadier did 80 metres of trenching across El Placer in three segments starting northeast of Los Lentes. Results include 8 metres of 2.14 g/t gold and 0.12% lead across the Tacuachas Vein (BRG-117146) and 4 metres of 1.95 g/t gold, 0.1% lead and 0.3% zinc across the surface of Los Lentes (BRG-117154). In addition to verifying the structures mapped underground, the surface trenches have identified gold anomalies between known veins that indicate the presence of several additional veins (Fig. 3). Assays for La Chivera, El Huarache and Pantufla are pending.

Fig. 3 Cross-section looking north-northwest across the El Placer Veins. Surface trench BRG-117146 is southeast of this section plane. It was cut off-section to go around an open pit that exploited the Tacuachas Vein. These surface data suggest that Tacuachas is the most important structure and that there are several unidentified structures between the veins known from historic underground mining. Surface trench samples are 1 metre wide.
