Project Location

Oxford lake Project
Numerous Drill Targets

Oxford Lake Project
Rusty Zone Cross Section
Oxford Lake, Manitoba

Highlights
  • Gold bearing structure traced for over 2 km in favourable geological setting
  • Historical resource estimate of 800,000 tonnes* averaging 6 g/t gold and containing 154,000 ounces
  • Other targets include Rusty Point with historical intersections of 4.6 g/t gold across 3.7 m and Blue Jay Island returning up to 10 g/t gold across 2.0 m
  • Drilling is required on Rusty Zone, Rusty Point and Blue Jay to evaluate their potential
* Historical Resource not compliant with NI43-101 standards

Location and Access

  • Located at the southwest end of Oxford Lake, approximately 160 km southeast of Thompson, Manitoba
  • Access is by float or ski equipped aircraft or by winter road
Geology
  • Archean age Oxford-Knee Lake Greenstone Belt in the western Superior Province of the Canadian Shield, including tholeiitic mafic volcanic and clastic meta-sedimentary rocks and banded iron formation units
  • Property lies along a major structural corridor that extends westward from the Rolling Rock Resources Monument Bay Deposit (4.89 million tonnes averaging 6.0 g/t gold to contain 944,000 ounces of gold) through the Oxford Lake Property
  • Gold is associated with sheared and sulphidized iron formation in a geological setting similar to the Musselwhite Mine as well as in shear hosted quartz veins
Size
  • 8,386 hectares
Ownership
  • 100% Alto Ventures Ltd

History

Exploration work on the property was conducted intermittently since the 1930s but the most comprehensive programs were completed by Noranda Exploration Ltd. between 1985 and 1991. The Noranda work resulted in the discovery of the Rusty Deposit. A historical resource (not compliant with NI 43-101 standards) was estimated to be 800,000 tonnes at 6 grams gold per tonne from 18 widely (100m to 300m) spaced holes.

Other mineralized zones were discovered on the property including Rusty Point where gold values up to 4.6 grams gold per tonne over 3.7 metre lengths were intersected in 1943 diamond drilling. In the late 1980's gold was intersected by Noranda in the Blue Jay claim, approximately two kilometres east of the Rusty Deposit. Values up to 10 grams gold per tonne over 2.0 m were intersected. These gold occurrences were not followed up with detailed drilling.

Two deposit models or mineralization styles can be applied to the Oxford Lake property. The first and currently most obvious is the sulphidized oxide-iron formation model for the Rusty Deposit and the Rusty Point and Blue Jay occurrences. The closest analogy for this style of mineralization is the Musselwhite Mine in north western Ontario. The second model includes gold in shear hosted quartz vein systems associated with tholeiitic mafic flows similar to the gold deposits mined in Timmins Ontario. This style of mineralization was not explored for in the past but supporting evidence is found in outcrops and some of the Noranda drill holes including RD90-38 where 9.2 grams gold per tonne over 1.3 metres were intersected.
