Quaterra Resources Inc. (now Lion Copper and Gold Corp.) continues to perform the work required to complete MacArthur's pre-feasibility study ("PFS"). The drill program announced on April 20, 2021 is the first major step toward completing the PFS.

Targeting the completion of the PFS by Q3 2022.

Deposit Type

  • Porphyry


Summary:

The MacArthur deposit is a supergene enriched, oxidized porphyry copper system. Although the porphyry system likely developed in near-vertical geometry, regional studies by Proffett and Dilles (1984) suggest the MacArthur area is tilted westerly approximately 60 to 90 degrees from its original vertical position and extended to the east so that the map view is actually a structural cross section. The original northwest strike of the near vertical porphyry dikes resulted in a northerly dip of the structures with the post mineral tilting.

Copper mineralization has been identified across nearly the entire area investigated by Quaterra’s drilling program at MacArthur and gives every indication of extending well beyond. As currently defined by drilling, copper mineralization covers an area of approximately two square miles as defined by drill holes on 500 feet to 250 feet spacing north of the MacArthur pit to approximately 150 feet spacing within the pit.

Oxide, chalcocite, and primary copper mineralization is hosted in both granodiorite and quartz monzonite, and in quartz biotite-hornblende (quartz monzonite) porphyry dikes all of middle Jurassic age. An insignificant percentage of oxide copper is also hosted in northwest striking andesite dikes that make up less than approximately one to two percent of the host rocks on the property. Fracturing and favorable ground preparation supplied the passage ways for the copper to migrate.

Mining Methods

  • Truck & Shovel / Loader


Summary:

Mining of the MacArthur deposit will be done by open pit methods utilizing a traditional drill, blast, load and haul sequence.

Approximately 271 million tons of mineralized material will be mined over the life of mine with an average waste to mineralized material ratio of 0.90. There are three final pits consisting of the main MacArthur pit, the North pit and Gallagher pit. Mining will start in the main MacArthur pit and progress to the North pit, then to Gallagher pit and ending at the outer limits of the main MacArthur pit in the last phase.
