MAKWA
Four styles of mineralization on the Makwa Property are summarized in Ferreira et al., 1999 and some smaller mineralized showings are discussed in Juhas, 1973:
1. Magmatic nickel-copper mineralization,
2. Sulphide iron formation nickel-copper mineralization,
3. Sulphide iron formation copper mineralization,
4. Chromite mineralization.

The Makwa deposit consists of disseminated pyrrhotite, pentlandite, chalcopyrite, and pyrite in an ultramafic peridotite layer at the base of the BRS (Ferreira et al., 1999; Harper, 2004). The higher grade mineralization near the footwall contact contains approximately 15% disseminated sulphide minerals. About 12% of the sulphides contains nickel.

The Makwa deposit strikes at approximately N60°E to N70°E and dips at -60ºS to -90º. The overall average strike is approximately N68°E, however, shorter segments appear to strike at approximately N62°E. The western part of the deposit, west of section 7+00W (original grid), strikes approximately 280° at surface and the strike progressively changes down to approximately the 500 ft elevation, where the overall deposit strike becomes more linear. The deposit dips at approximately -70°S or less at the northeast and southwest extremities and dips at -80°S or steeper from approximately section 3+00W to section 8+00W (original grid). The deposit is approximately 500 m long by 10 m wide and extends to at least 500 m below surface. The deposit appears to hav ........

The PEA is based on open pit mining with production from a single pit at the Makwa Property, followed by a single open pit at the Mayville Property. Pit benches will be five metres high for Makwa and ten metres high for Mayville. The mineralized material and waste rock will be drilled and blasted, loaded with front end loaders, and hauled to either a crusher or waste rock pile. Haulage distances from the open pit to the crusher area will vary. The Makwa ROM will be trucked approximately 43 km to the Mayville concentrator facility. Mayville ROM will be hauled approximately one kilometre to the concentrator.

It is estimated that the mine will operate on a general production schedule of 24 hours per day, seven days per week. Production blasts are scheduled to occur five to six days per week. Mine life is four years for Makwa and eight years for Mayville, and the mining rate will average approximately 20.5 million tonnes per year of mineralized material and waste mined.

Vegetation and topsoil will be cleared by dozers and graders preceding the mining operation. Suitable growth media material will be stockpiled for future reclamation use. For estimation purposes, it was assumed that a two metre thick layer of growth media is present on the Makwa and Mayville resource areas. When stripping activities are started, the actual thickness of the growth media will be determined, and the appropriate amount set aside. If any overburden needs to be stripped, then fro ........

The concentrator consists of conventional multistage crushing followed by two stage grinding in closed circuit with hydrocyclones.
