BlackRock Metals is a Canadian critical minerals company which is in the final stages of planning the construction of an integrated, environmentally conscious manufacturing operation processing critical minerals and producing green products in its state-of-the-art facilities in Saguenay and from it’s wholly-owned vanadium, titanium and magnetite (“VTM”) deposit in Chibougamau, Quebec. |

Summary:
The BlackRock Metals deposit is an Fe-Ti-V oxide deposit associated with a mafic layered intrusion. It is located in the Lac Doré mafic layered intrusion located approximately 20 km south of Chibougama, at the southeast end of the Abitibi subprovince of the Superior geological province. The genesis of this deposit type is related to processes of fractional crystallization where layers rich in oxides (especially Fe and Ti) settle out by magmatic segregation in large mafic intrusions.
The Lac Doré complex stretches northeast to southwest over a distance of about 24 km, with BlackRock Metals holding the rights to about 17 km. It is deformed by a large anticline and metamorphosed to the schist facies, as are the volcanic rocks that host it. The mineralized zone consists of gabbro rich in magnetite ilmenite (vanadiumferrogabbros) rhythmically layered with anorthosite beds.
Two main mineralized zones have been identified on the BlackRock Metals property: the Southwest Zone and the Armitage Zone, which cover 2.5 km and 3.3 km sections of vanadium-bearing ferrogabbro horizons, respectively. BlackRock Metals’ current development efforts are focused on the Southwest Zone.
The oxide-rich layers of the Southwest Zone have been exposed in multiple trenches on surface and intersected in more than 60 diamond drill holes. The resulting mineralized envelope characterized by BlackRock Metals ranges in thickness from some 100 to 300 m. The geological sections ........
Summary:
As the deposit outcrops on surface, the ore will be mined by open pit. The pit will be oval and elongated in shape, about 2.8 kilometres long by a maximum of 450 m wide and about 280 m deep. The surface of the pit will therefore cover about 1.26 km2 . The roads in the pit will be 34 metres wide to allow the 220-tonne trucks to pass each other safely. The roads will have a maximum slope of 10%. Vehicles will exit the pit to the southwest, near the facilities.
At full capacity, BlackRock Metals plans to mine about 12.4 Mt of ore per year to produce 3 Mt of concentrate per year. At the end of operations, 152 Mt of ore, 264 Mt of waste rock and 7.6 Mt of overburden will have been extracted to produce 38 Mt of concentrate.
