Snapshot	The Artillery Peak Property: a manganese prospect approximately 251 hectares in size, located in the Artillery Mountains of Mohave County in northwestern Arizona, about 170 kilometers northwest of the city of Phoenix. The Artillery Peak Property is subject to a 2% net smelter return royalty, and a pre-feasibility study was completed on it in 2012. Due to manganese prices being low, we have not proceeded with any further exploration or development for the project. As at July 31, 2019, RecycLiCo Battery Materials elected to write off the balance of the remaining costs down to a nominal value.

Deposit type

• Vein / narrow vein

Summary:

Two distinct styles of manganese mineralization are observed on the Property: stratiform manganese deposits, and vein manganese deposits. The mineralization style responsible for the majority of manganese on the Property is stratiform manganese, which occurs within the Chapin Wash Formation. These deposits have typical grades of around 3% to 4% Mn and locally 6% to 10% Mn. Some workers interpret these deposits to be syngenetic with the host sediments, whereas others interpret remobilization of manganese and potassium by secondary metosomatic fluids. Some secondary redistribution of manganese occurred because of interaction with meteoric water.

Manganese also occurs within veins, breccias (some of which have been interpreted as possible volcanic vents), and fracture and fault zone cement, and overall this style of mineralization is referred as vein manganese. Mineralized veins are locally common within or near the stratiform deposits although they do occur in other units in addition to the Chapin Wash Formation, particularly within the Sandtrap Conglomerate. Vein manganese deposits are several million years younger than stratiform deposits, and although they are not obviously related, their spatial association does suggest some genetic link. Vein-type deposits are smaller, irregular and locally higher grade than the stratiform deposits and their size currently does not support large tonnage bulk mining practices.
