Historical Overview
The Brosnor mining property is comprised of a group of 18 claims, totalling 922,8 ha, located in the Louvicourt Township, approximately 30 kilometres east of the town of Val d’Or, in the province of Quebec. The numbered company has been instrumental to sign the option agreement with GYG Ltd and to roll that option to Tech Solutions Capital Corp. against a share exchange agreement. .
The property is readily accessible by main and secondary roads and without any geomorphologic, environmental or cultural restrictions. It lies within an archean Abitibi volcano-sedimentary belt, Superior Province, composed of a sequence of mafic to ultramafic horizons known as the Jacola Formation, in which major regional shear zones, striking roughly east-west can be traced for many kilometres. Some of these structures are hosted by relatively more competent mafic volcanics, creating brittle deformation and open spaces favourable for trapping gold mineralization composed of quartz, tourmaline and pyrite as vein material deposition by hydrothermal solutions. Gold is mostly linked to pyrite as inclusions and rarely free. The mineral deposit model of the property, linked to shear zones cutting across fractured competent volcanic/diorite at contact with ultramafic rocks is alike to the Kerr-Addison (Larder Lake) or Astoria (Rouyn-Noranda) ore deposit.
Prospecting of the Brosnor property dates back to 1945, the date of the first gold discovery by diamond drilling. Till 1987, 14 different companies carried exploration programmes, and from then to present, the property titles changed hands five times with either junior mining companies or individuals but no field work executed. The amount of drilling on the discoveries (more than 300 holes and 140 000 feet) and an underground development programme witnessed of the activities that cut short with the doldrums of the mining exploration by the end of the eighties.
Over 400 files covering activities on and around the property were consulted, a large quantity as GM file numbers at the government office in Québec, as private reports from the seller, GYG, and in offices of former owners in Val d’Or and Rouyn-Noranda. A property site visit and core examination and check sampling were also executed.
The first intense exploration activity between 1945 and 1950, lead to the discovery of the two known main gold deposits, namely the Adelemont and Norcourt zones, some 500 meters apart, along the same east-west shear. The mineralized bodies dip steeply to the south across the steeply north dipping stratigraphy. An additional one, the Bermont zone, some 500 meters to the south-west of the Adelemont, was discovered in 1964.
From then till 1980, not much exploration was executed. The second period of intense activities occurred between 1980 and 1987, under the ownership of Canadian Brosnan Mines Ltd who drilled 200 holes mainly on the Adelemont and Norcourt zones. During that period, the property was optioned by Mining Corp. of Canada (1981-1984) who reported in 1982 the first historical resources calculation, estimating at 277 503 tons grading 0,119 oz/t Au the Adelemont deposit and at 34 352 tons grading 0,124 oz/t Au the Norcourt zone, those probable resources (not complying with NI 43-101) to a depth of 550 feet.
There after, much drilling has been conducted and Brosnan, in 1986 sank a decline 680 meters long to a vertical depth of 100 meters in the Adelemont deposit. The development ended in mid 1987.
From 1987 to this day, the property changed hands five times without any exploration work executed and contributed to the losst of important documents namely the complete set of cross and longitudinal sections based on which the recorded resources calculations were calculated.
In the spring of 2007, 0787912 B.C. Ltd. executed a minimal verification drilling programme that successfully intersected the mineralized Adelemont deposit and also supported its reported westward and down depth extensions. One hole also located the underground development openings.
The main Adelemont deposit forms a lens 90 meters long, 2,6 meters wide and traced up to the -300 meters level. The mineralized lens plunges 65 degree to the west and is opened to the west and down plunge. The Norcourt zone, on the other hand, appears to be more restricted and discontinuous. Finally, the Bermont zone is at an earlier stage of exploration with restricted drilling after its discovery in 1964, but contain many intersections with good grades, above 0,10 oz/t Au over lengths of 10 feet, as witnessed by a check assay of 0.80 oz/t over a length of 14 feet (sample B-4).
