Boss Mountain Project (British Columbia)

A project in exploration stage for moly and copper

Overview

NMC Resource Corporation ("NMC Resource") has entered into option agreement for the acquisition of 100% of Boss Mountain Mine (the "Property" or "Boss Mountain") in British Columbia. Boss Mountain was operated by Noranda Mines Ltd. ("Noranda") to produce molybdenum ("Mo"), at average grades ranging from 0.19% Mo (0.32% MoS2) to 0.26% Mo (0.43% MoS2), from the 1960's to the mine closure in 1983 due to low Mo price.

Location

The Property is located approximately 250 kilometres southeast of Prince George, BC and 85 kilometres east of Williams Lake, BC within Cariboo Mining District.

History

Boss Mountain was first located in 1917. The Consolidated Mining and Smelting Company acquired Boss Mountain in 1930 and the claims were sold for taxes in 1955. Climax Molybdenum Corporation explored Boss Mountain during 1956 to 1960. Between 1956 and 1959, geological mapping, a geophysical survey, trenching, and 9,753 metres of diamond drilling were conducted at Boss Mountain. In 1961, Noranda purchased the rights to operate Boss Mountain and produced Mo until 1983.

Geology

The molybdenum deposit occurs near the eastern margin of the Early Jurassic Takomkane batholiths, which intrudes Upper Triassic Nicola Group volcanic rocks on the south and west, and is in fault contact with Lower Jurassic volcanic and sedimentary rocks to the east and north. The Takomkane batholith is composed of a syenodiorite phase, a granodiorite phase and a porphyritic biotite granodiorite phase. Intruding the batholith about 450 metres northeast of the deposit is the Cretaceous Boss Mountain Stock of porphyritic quartz monzonite. Related to this intrusion is a complex sequence of rhyolite porphyry and rhyolite dike emplacement, breccia development and molybdenum introduction. Molybdenum mineralization is contained within quartz veins and breccia bodies within the granodiorite phase of the batholith.

Molybdenum Deposit Type

Porphyry Mo (low-F type): BC Mineral Deposit Profie L05

Infrastructure

Boss Mountain can use existing infrastructure including roads, local labour sources and a tailings dam that still has capacity to store additional tailings. The Property is close to beautiful towns, Williams Lake and 100 Mile House, which can serve employees and their family.
