Mouse Mountain Project Overview

Thomspon Nicket Belt

CanAlaska has acquired three properties in the Thompson Nickel Belt: Strong, Hunter and North Manibridge.

The Thompson Nickel Belt is the host of over 18 nickel deposits and is estimated to have produced over 5 billion lbs of nickel since 1959. The nickel deposits are hosted in the Opswagan Group, a sulphide-rich metasedimentary package intruded by ultramafic intrusions. The nickel deposits are located within the ultramafic sills or in the metasediments proximal to the sills.

Figue 1 shows the geology of the Thompson Nickel Belt and the location of the main nickel deposits, north of the Paleozoic cover under which the belt continues to the South.

Figure 2 shows the stratigraphy of the Opswagan Group. The main unit of interest is the Pipe Formation, the lower part of which is rich in sulphides, and hosts most of the ultramafic sills and nickel deposits.

Figure 3 illustrates the geometry of the ultramafic sills and nickel deposits, the end result of the process leading to the formation of these deposits.

Hunter Property

The Hunter Project consists of one Mineral Exploration License totaling 6,176 hectares, located 15km north of Thompson, Manitoba (Figure 4).

Geology

The area is underlain by the same series of formations that host the nickel deposits along the Thompson Nickel Belt and considered to be an extension of this Belt.

Historical Exploration

The project area was explored by a variety of companies in the 1950's to the 1970's which led to the discovery of the Mel deposit located immediately to the East of the Hunter property. Inco (Vale) explored the Hunter property and the Mel area from 1999 to 2005 in JV with Nuinsco Resources Ltd (Victory Nickel)

CanAlaska Exploration

Significant exploration targets have been defined on both properties based on a compilation of historical exploration. Extensive UTEM and AMT surveys in 2000-2005 have resulted in a number of drill targets, only some of which have been drilled. Some of the nickel intersections form older drilling also require follow-up.

Potential

The Thompson Nickel Belt is the fifth largest nickel mining in the world. Past production from these deposits is 2.5 Mt Ni. The potential of this project is for nickel deposit equivalent to the Thompson or Birchtree deposits still being mined by Vale.
 

STRONG PROPERTY

Historical Spend >$5M

Location

The Strong Project consists of one Mineral Exploration Licenses totaling 6,140 hectares, located 26km north of Thompson, Manitoba (Figure 4).

Geology

The area is underlain by the same series of formations that host the nickel deposits along the Thompson Nickel Belt and considered to be an extension of this Belt.

Historical Exploration

The project area was explored by a variety of companies in the 1950's to the 1970's which led to the discovery of the Mel deposit located immediately to the East of the Hunter property. Falconbridge, in JV with Crowflight Minerals Inc (CaNickel Mining Ltd) was active on the Strong Property from 1998 to 2005. In 2007 Crowflight flew a VTEM survey that was processed in 2008 by Condor Consulting.

CanAlaska Exploration

Significant exploration targets have been defined on both properties based on a compilation of historical exploration. The VTEM survey completed in 2007 and processed in 2008 has provided a series of targets, none of which have been drilled. Several of these targets are in the same structural position as the Mel deposit.

Potential

The Thompson Nickel Belt is the fifth largest nickel mining in the world. Past production from these deposits is 2.5 Mt Ni. The potential of this project is for nickel deposit equivalent to the Thompson or Birchtree deposits still being mined by Vale.

NORTH MANIBRIDGE PROPERTY

Location

The North Manibridge Project consists of 15 claims totaling 3800 hectares, located 125km south west of Thompson, and 32km southwest Wabowden, Manitoba. It is accessible by road from highway 6 (Figure 5). The claims are adjacent to the Manibridge Mine claim.

Geology

The area is part of the Thompson Nickel Belt and contains the same formations as the Thompson Mine area.

Historical Exploration

The area has been explored for nickel since 1960, starting with an airborne survey by Falconbridge. The Manibridge deposit was discovered shortly thereafter and production decided in 1969. Exploration on the North Manibridge claims consisted in geological mapping, geophysics and drilling predominantly by Falconbridge from the 1970's to the 1990's. Inco staked the area in the early 2000's and carried out ground geophysics.

CanAlaska Exploration

Significant exploration targets have been defined on both properties based on a compilation of historical exploration. The VTEM survey completed in 2007 has provided a series of targets, none of which have been drilled that correspond to an area with nickel mineralized drill holes (see Table 1 below)

Potential

The Thompson Nickel Belt is the fifth largest nickel mining in the world. Past production from these deposits is 2.5 Mt Ni. The potential of this project is for nickel deposit equivalent to the Thompson or Birchtree deposits still being mined by Vale.
