Drilling and Surface Sampling Results Indicate Primary Vein System Contains Over 7 Kilometres of Robust Mineralization.
Drill Assay Results from Other Previously Untested Prospective Zones Expected During January.
Vancouver, British Columbia – January 19, 2021 – Brigadier Gold Limited (the “Company” or “Brigadier”) (TSXV: BRG|FSE: B7LM|USA: BGADF) is pleased to provide additional diamond drill and surface sampling results from ongoing phase one exploration at its Picachos gold-silver project, Sinaloa Mexico (the “Picachos Project” or the “Property”). Brigadier has completed 3085 metres of diamond drilling in 28 holes on the Picachos Project. Assays are now available for 20 holes (Table 1), and samples from the remaining holes are in-progress at SGS Laboratory in Durango.
Drilling highlights include:
- 9.49 g/t Au and 24 g/t Ag across 3 m (88 to 91 m) in DH-BRG-008
- 6.24 g/t Au and 79 g/t Ag across 3 m (122.5 to 125.5 m) in DH-BRG-009
- 7.03 g/t Au and 110 g/t Ag across 3.5 m (137.5 to 141 m) in DH-BRG-012
- 6.75 g/t Au and 44 g/t Ag across 2.5 m (108.5 to 111 m) in DH-BRG-014
Geologist and Qualified Person Michelle Robinson comments “I am really pleased with our results so far from San Agustín. The structure is persistent and strongly mineralized. Although our sampling with a diamond drill is not perfect due to the challenging sub-surface conditions, it definitely indicates a robust gold-bearing vein of substantial width and strike length of over seven kilometers. I look forward to expanding the depth and strike length in 2021, as well as continuing the exploration of the rest of the CVS (Colomeca Vein System), particularly in the central Cocolmeca area where a swarm of northwesterly trending veins intersects the east-north-easterly trending Cocolmeca Vein System.”
Ranjeet Sundher, President and CEO, also comments “We are impressed with the speed in which Michelle and her team is de-risking the Picachos Project and increasingly demonstrating its regional scale potential. With just a small portion of the asset explored to date, I’m looking forward to keeping shareholders abreast as we aggressively move forward to further define the Colomeca Vein System while also commencing examination of the large copper-molybdenum porphyry target located on the northern part of the Property.”
Of the 28 holes drilled to date, fourteen (1704.28 metres) were drilled to test the San Agustín Vein, 10 holes (1029 metres) tested surface exploration targets defined by trenching, 2 holes (168.5 metres) tested under the historic San Antoñio Mine and one hole tested under the historic La Gloria Mine. San Agustín and San Antoñio represent two gold-rich, polymetallic mineral chutes about 2.5 kilometres apart on Brigadier’s regional-scale Cocolmeca Vein System (CVS), and La Gloria historically produced gold from a northwesterly trending vein roughly orthogonal to the CVS. The CVS has been defined at varying levels of certainty along the east-northeasterly trending diagonal of the Picachos Project for more than seven kilometres. Six surface rock chip-channel results that help define the location of the CVS include:
- 4.89 g/t Au and 67 g/t Ag across 5 metres (trench BRG-104705) from San Agustín (PR dated 24 November 2020)
- 1.85 g/t Au and 4 g/t Ag across 10 metres (trench BRG-120920) at Los Tejones prospect pits, centered 1 kilometre northeast of San Agustín
- 347 g/t Ag, 0.1 g/t Au and 5.2% Cu across 1.0 metres (historic trench MTA-15953) at Guayabo, 2.4 kilometres northeast of San Agustín
- 44.09 g/t Au and 47 g/t Ag across 0.8 metres (historic trench MTA-19856) at San Antoñio, 2.5 kilometres northeast of San Agustín
- 5.25 g/t Au and 74 g/t Ag across 1.2 metres (trench BRG-27012) from the road to La Botica, 3.7 kilometres from San Agustín
- 1.9 g/t Au and 98 g/t Ag across 1.6 metres (trench BRG-25220) from El Pino, 5.8 kilometres northeast of San Agustín (PR dated 14 September 2020)
Figure 1. Overview map of surface results 1 to 6 (above) on the surface trace of the CVS, highlighted in yellow. Locations of 2020 diamond drill sites are marked in black circles labeled DH. Holes 26 and 27 are below trench site 4 (MTA-19856). The Picachos Project boundary is in navy blue. The internal concession that is held by a subsidiary of Fresñillo PLC is marked in grey. The yellow CVS dips northwesterly, into the center of the Property.
During the Fall of 2020, the Company primarily explored the down-dip potential of the southwestern most segment of the CVS that was historically exploited by Minas de Picacho from San Agustín Adit Level 646 in the 1990’s. Three fences of holes were drilled up to 130 metres north of this adit, and three fences were drilled up to 90 metres south of Level 646. Overall, a strike length of about 210 metres was tested. Most mineral intercepts were located between 650 and 550 metres elevation. The deepest test was in DH-BRG-007 at 530 m elevation or 200 metres below topography.
Geologically, the mineralization is located at the faulted and sheared contact between metamorphosed, thickly laminated, sulfide-rich argillite of deep marine origin and porphyritic intermediate continental volcanic rocks correlated to the Tarahumara Formation. Fault damage on this regional-scale geological terrane boundary is profound with shearing and quartz veining evident at several locations in the hanging wall to the San Agustín Vein. On Figure 3, a preliminary interpretation of what this veining might look like is shown in the rose color in the Picachos Project fault block. Some results from quartz veins and veinlets in the hanging wall to the San Agustín Vein are:
- 2.71 g/t Au and 24 g/t Ag across 2 m (54 to 56 m) in DH-BRG-003
- 0.6 g/t Au and 34 g/t Ag across 2 m (52 to 54 m) in DH-BRG-005
- 0.73 g/t Au and 27 g/t Ag across 4 m (51 to 55 m) in DH-BRG-014

Figure 3. Level Plan of the San Agustín Vein. All 14 diamond drill holes intercepted gold-rich polymetallic mineralization at the faulted contact between metamorphic argillite of submarine origin (blue) and altered continental volcanic rocks correlated to the Tarahumara Formation (greens). In the hanging wall (Picachos Project fault block), there are several quartz veins and veinlets hosted in the argillite. In rose, a possible interpretation for some of the hanging wall intercepts is shown.
At Los Tejones, encouraging results of 1.85 g/t Au were cut across 10 meters in a surface trench (BRG-120920). About 50 meters to the northeast, a second trench cut 1 meter of 428 g/t Ag (BRG-119913). Rock discovered by both trenches was deeply weathered and structures controlling the mineralization were mostly not obvious. Drill testing under these anomalies returned anomalous base metals but subdued precious metals (DH-BRG-015 to 20). Geologically, disseminated and stockwork mineralization occurs at the faulted contact between magnetic andesitic volcanics that might be Jurassic in age, and intermediate volcanic rocks correlated to the Tarahumara Formation.
Results from other surface trenches include:
- 2.09 g/t Au and 170 g/t Ag across 1.2 m from the Casimiro Vein (BRG-27024)
- 8.84 g/t Au, 36 g/t Ag and 1.6% Pb across 2 m from El Roque Vein (BRG-120828)
- 5.25 g/t Au, 74 g/t Ag and 1.7% Cu across 1.2 m from La Cocolmeca Vein (BRG-27012)

The Picachos Project land package was methodically assembled by Michelle Robinson (MASc., P.Eng., Geologist, 43-101 QP) over 10 years ago. Michelle is a respected industry veteran who has worked in Mexico for over 20-years with a number of major mining companies. She has authored over 20 technical reports and published several papers for the Society of Economic Geologists. Michelle and her team are executing on our 5,000-metre diamond drill program – the first ever on this project
The Picachos Project’s location, situated 25 kilometres equidistant from two recent bonanza grade discoveries of Vizsla Resources and GR Silver and along the same mineralized trend, positions Picachos Project as a truly exciting opportunity for Brigadier and our shareholders.
The 3,954 hectare Picachos Project is centered over the historic “Viva Zapata” National Mineral Reserve, Sinaloa, Mexico. It overlaps two mineralized systems, a porphyry copper-molybdenum system hosted by a Paleocene granite-granodiorite intrusive complex, and a gold-silver vein complex comprised of both east-northeasterly trending veins (La Cocolmeca Vein System) and northwesterly trending veins (El Placer System). Sericitic alteration related to the porphyry system has been mapped over the northwestern two-thirds of the Property. Quartz-biotite veinlets with chalcopyrite and bornite occur in the central part of this broad zone of sericitic alteration and imply the presence of a significant porphyry system at depth. La Colcomeca Vein system has been mapped from San Agustín Underground Gold Mine in the southwestern part of the Property to El Pino seven kilometres to the northeast. In the central part of the Property, the best exposure of the northwesterly trending system occurs between La Gloria Underground Gold Mine and the Urrea Gold Mines, located 630 metres southwest of La Gloria. In this area, other northwesterly trending veins between these veins include Paldodismo, Colorin, Salvador, Trompetas and Mangos. On the eastern part of the Property, Tatemales and La Botica define a four kilometre long trend.
The growing inventory of priority drill targets underscore the untapped potential of this particular region of Sierra Madre Occidental epithermal belt.
