Picachos Mine Project Vista

Picachos Project

Brigadier’s 100% controlled Picachos project is a 3,954 hectare gold and silver prospect located in Sinaloa State, Mexico

Prior to 2002, the mineral tenure was fractured by several small concessions until they were assembled into a contiguous land package between 2003 and 2012.

Picachos hosts over 160 underground historic mines, workings and prospects which have yet to undergo modern, systematic exploration and drilling.

Primary targets include under-explored gold veins within the historic San Augstin mine and La Gloria, a historic mine with rock samples containing 21.1 g/t Au and 6 g/t Ag across 0.8m (Sample #15659)

The 3954.1 Ha Picachos Property overlaps a significant porphyry system centered in Southern Sinaloa State, Mexico, near geographic co‐ordinates 105º45’W and 23º12’ N. Mining concessions that define the Property were acquired by staking between 2003 and 2012 over the former “Viva Zapata” Mineral Reserve, a project that was staked and explored by the Servicio Geologico Mexicano in the 1980’s (Bon‐Aguilar, 1987 and Rodriguez‐Rodriguez et al., 1984).

Geographically, the Property overlaps part of the western foothills of the Sierra Madre Occidental, one of the world’s largest silicic igneous provinces (Aranda‐Gomez et al.,2003). Regional geochemical work by the SGM at the turn of the millennium highlighted the Reserve as one of the largest contiguous anomalies for gold and base metals in southern Sinaloa and Northern Nayarit.

Detailed Gold Geochemistry in Stream Sediments

Picachos is situated on one of the largest high-amplitude contiguous anomalies for gold and base metals in the western Sierra Madre with values up to 6841 ppb Au in fine-fraction, active channel stream sediments

Anomalous drainages are on the northeasterly trending Cocolmeca Fault (San Agustin historic mine) and northwesterly trending veins related to Oligocene and Miocene extension (El Placer, Mirador).

Centered over the historic “Viva Zapata” National Mineral Reserve due east of Mazatlán.
26 km NE of Cacalotan in the Municipio of Rosario, Sinaloa.
Access is via a paved road between the historically active gold mining town of El Rosario and the village of Cacalotan. From there, a 26km-long country road trends northeasterly to the hamlet of Sitios de Picacho.
Mine workings are accessed from about 20 kilometers of roads internal to the Property.
On 27 June 2020, the Minera Camargo S.A. signed a renewable five-year Agreement with the Ejido of Picachos granting full access to Ejido lands overlapping the concessions for activities permitted under mining law.
In the mid-1990’s, Minas de Picacho built 225 m of cross-cuts large enough for rubber-tired diesel equipment and started mining and milling ore from the San Agustin Gold Mine.

Geology

Regional Gold Geochemistry

Inspection of the fine fraction stream sediment data (Source: Servicio Geologico Mexicano) for the western Sierra Madre shows that the Picachos Property overlaps one of the largest, most contiguous, and highest amplitude anomalies for gold, silver and base metals in the Western Sierra Madre.
Specifically, nine drainage basins that overlap a combined contiguous surface area of 3644 Ha (range 70 to 892 Ha) with gold concentrations ranging from 133 ppb to 2595 ppb Au underlie the Property. Copper values range from 35 to 299 ppm, lead ranges from 44 to 639 ppm and zinc values range from 116 to 1716 ppm.

Property Geology

Rocks mapped as Lower Tarahumara might actually be part of the Guerrero metamorphic basement. These rocks are intruded by trachydiorite or gabbro.
Late Cretaceous to Paleocene volcanics include andesitic and rhyolitic lithologies correlated to the Tarahumara Formation (Montoya-Lopera et al., 2019). Some of these older ignimbrites were previously mapped as Oligocene. A recent U-Pb zircon date of 74 Ma from the Cobre Vein area was determined by the University of Arizona.
Areas mapped as Miocene granodiorite by the SGM are now known to be Paleocene. A U-Pb zircon age of 66 Ma was determined by the University of Arizona for a sample taken northeast of Mochomos. Paleocene intrusions are related to porphyry deposits elsewhere in the SMO.

~665 meters of historic underground development.
Stoped area has dimensions of about 100 m long, 80 m high and two meters wide.
Underground sampling by Thunderbird Projects implies an average grade of 81.22 g/t Au and 73.36 g/t Ag across 1.2m (18 June 1997 News Release).
MCA (concession owners) produced about 1850 tonnes of muck from a shaft 12m long, 1.5 m wide and 45 m deep at the end of the main level (JJV Slot). Values from the bottom of this shaft were 185 g/t Au.
In June of 2014, Vane Minerals test mined three rounds from the south face. The average assay values of these three rounds were 15.8 g/t Au and 63 g/t Ag across a width of 2.5 m.
Gold can be recovered by (i) gravity, (ii) flotation (with sulfides; > 82%) and (iii) with cyanide (> 90%).

San Agustin Mine Main Extraction Level 646

Gold from crushed and panned rock in the shear zone.

La Gloria is a historic gold mine developed on one of many NW trending veins exposed on the northwest face of Cocolmeca fault scarp.
Main level is a 103 m long easterly trending tracked tunnel about 2 m high and 2 m wide at 950 m elevation that cross-cuts a NW trending structural zone hosted in argillic altered rhyolite breccia.
Open stope is > 150 m long and breaks through to surface at 1038 m elevation.
Rock sample 15659 (left) contains 21.1 g/t Au and 6 g/t Ag across 0.8m.
Gold mineralization (electrum) occurs in a structural zone characterized by 10-20% red chalcedonic quartz hematite veinlets that contain minor bright green zinc-copper oxides and hematite stain.
Modeling and full results summary are in-progress.

Killala Lake Project

Brigadier Gold Ltd. has entered into an option agreement with Rudolf Wahl and Mike Dorval, together doing business as the Wahl Group, to acquire a 100-per-cent interest in the Killala Lake South diamond property, consisting of 46 cell claim units located in Killala Lake, Foxtrap Lake area townships, Thunder Bay mining district, Ont., subject to reservation of royalties in favour of the Wahl Group.

A 1 tonne sample was taken and processed at Kennecott DMS plant in 2007-2008. Over sixty macro diamonds, including eight commercial sized diamonds were recovered. Colours included white, green, yellow, brown and grey diamonds with an average grade of 0.23 carats for the first sample taken. About half of the one tonne sample was taken from the fine-grained, chilled margin portion of the dyke from which one would expect a low diamond carrying potential.

The dyke is approximately 1 to 2 meters wide at outcrop with strike/dip-direction at 009/065. The rock is macro-cryptic and dark comprised of approximately 20% olivine (up to 0.5cm), up to 2% garnet with reaction rims (0.2 cm), and minor cox in dark grey crystalline matrix. Magnetic susceptibility values ranged up to 10 SL. Some highly weather/baked country rock xenoliths were present. The dyke is layered or branded and contains both macro-crystic portions and non-macro-crystic bands, which are generally closer to the contact. The Majority is macro-cryptic. The dyke can be traced in outcrop for approximately 50 meters.

The dyke intrudes into granitoids with <0.5 SI magnetic susceptibility, and dips 65 degrees at the hanging wall and 78 degrees at the footwall, so the diamond bearing dyke will have a larger width at depth.

A ground magnetic survey and MMI survey was created within the surrounding area of the diamond dyke. These survey’s outlined a large kimberlite pipe target just to the south of the diamond dyke and other kimberlite targets within close vicinity of the diamond bearing dyke.

One sample taken over 60 macro diamonds including 8 commercial sized diamonds 0.23 carats

A 1,205.80-kilogram sample of the material was taken from the dyke. The results of this sample yield a total of 66 diamonds, including 21 stones greater than 0.5 millimeters in size and 8 stones greater than0.85 mm in size.
