Maskwa Project

Results of the National Instrument 43-101 compliant Preliminary Economic Assessment ( commonly known as a “Scoping Study” ) were released January 2007.  The Scoping Study was prepared by Micon International Limited who are a leading geological engineering firm.  A Scoping Study is completed in order to determine the economic feasibility of bringing the Maskwa Project into production. The Scoping Study is posted on sedar.com.

Prefeasibility Study

Mustang is currently completing a prefeasibility study for the Maskwa project. The following consultants have been engaged to complete the prefeasibility study:

Wardrop Engineering (Mine Design,Geotechnical and Resource Model)

Golders Associates Ltd (tailings disposal)

F Wright Consulting Inc (metallurgical work)

Met-Chem Canada Inc. (Metallurgy and Process Definition, Ore Processing Facilities and Mine Site Infrastructure).

An active exploration program is ongoing in the resource area and beyond. Initial drill targets include areas immediately adjacent to the known areas of mineralization both on the west and east limits of the resource. Additional exploration potential exists at depth and in potential feeder structures.

Additional Property History

1952-1957: Falconbridge subsidiary Maskwa Nickel Chrome Mines drills 75 holes totaling about 25,000 feet.  Discovers Dumbarton Nickel and F-Cu Deposit.

1969-1974: Dumbarton Deposit produced 1,697,000 tons @ 0.81% Ni (27,491,000lbs.) and 0.31% Cu (10,521,400 lbs.). Cobalt and platinum palladium credits were unspecified.

1974 –1976: Maskwa Nickel Chrome Mines Limited drills 97 holes totaling about 50,000 feet discovering the Maskwa Nickel Deposit.  The Maskwa Nickel Deposit produced by open pit 365,730 tons @ 1.16% Ni (8,484,936 lbs.) and 0.20% Cu (1,462,920 lbs.) to a vertical depth of150 feet.

1996-2000: Canmine Resources Corporation acquires the property from Maskwa Nickel Chrome Mines. Completes geological, geophysical and diamond drilling surveys.  Maskwa Nickel Deposit resource estimated at 2,929,911 tons @ 1.27% Ni (74,419,739 lbs.), 0.21% Cu (12,305,626 lbs.), 0.04% Co (93,757 lbs.), 0.009oz/t platinum (26,369 ounces) and 0.031oz/t palladium (90,827 ounces).

Regional Geology

The area is underlain by the Archean aged Bird River greenstone belt which consists of east-west trending metavolcanics and metasedimentary rocks and Syn- to late tectonic intrusions, notably, the Bird River Sill.

Property Area Geology

The major stratigraphic feature on the property is the layered Bird River sill which is one kilometer thick and extends across the property, a distance of 8.0 kilometers.  The Bird River sill hosts the Maskwa Nickel Deposit along its basal contact.  The Dumbarton Nickel Deposit and F Zone Copper Deposit are hosted along the basal contact of the underlying mafics in contact with a sulphide facies iron formation. The property is cut by numerous north–south trending faults and block faults.
