NICKEL OFFSETS PROPERTY

100% interest held by United Reef. In March 2008 URSA Major was granted an option to earn a 70% interest in the property by making $1.25 million of exploration expenditures over 3 years and total cash payments of $75,000 to United Reef.
URSA Major has provided United Reef with details of their proposed initial exploration program which includes a five hole, 1,800 meter diamond drilling program to test potential sulphide bearing environments within the Foy Offset dyke, all occurring in close proximity to the existing workings of the former Nickel Offset No.1 Mine. Prior to drilling, bore hole geophysical surveys will be carried out to test for conductive targets. The drilling program is scheduled to commence in early summer 2009 and will be completed by October 28, 2009.
Consists of 12 patented claims (358.5 acres) and 5 unpatented mining claims (525 acres) within Foy Township, Ontario, 40 km NNW of Sudbury.
Straddles a 2.25 km strike length of the Foy Offset, the largest radial offset dike emanating from the Sudbury Igneous Complex.
Unpatented ground covers the Foy Offset dike to a projected depth of 2,000 metres.
The property includes the past-producing Nickel Offsets Mine (1943–1957).
Historic records indicate extensions of mined ore lenses may remain in place.
Located in the Sudbury mining camp which has historically produced in excess of 16 billion lbs Ni, 15 billion lbs Cu, 85 M oz Ag, 17 M oz Pt, and 3 M oz Au.
Exploration neighbours include Aurora Platinum, Falconbridge, Wallbridge and Inco.

NICKEL OFFSETS MINE

Produced over 208,000 tons of Ni-Cu ore (4,576,138 lbs Ni, 3,327,299 lbs Cu) from 1943 to 1957.
2 shafts 3,000 ft apart
- Shaft 1: 1,599 ft deep, 10,000 ft of drifts and crosscuts, 3,980 ft. of raises, 9 levels;
- Shaft 2: 1,106 ft deep, 6,000 ft of drifts and crosscuts, 409 ft. of raises, 5 levels.
Pre-production reserves: 359,000 tons @ 1.91% Ni, 1.45% Cu, and $1.98 per ton in precious metals (1940 metal prices).
Smelting contract with Falconbridge in the 1950’s required high-grade Ni concentrates with a minimum cut-off.

PROPERTY GEOLOGY

The Foy Offset dike consists of quartz-diorite and quartz-diorite breccia with known Ni-Cu mineralization.
Similar geology to host rocks of Ni-Cu-PGE deposits at Inco’s Copper Cliff North (Copper Cliff Offset) and Totten mines (Worthington Offset) and FNX Mining’s Powerline Deposit (Worthington Offset).
The dike dips steeply, averaging 75-80º to the north with a known down-dip continuity to depths of at least 750 m.
Aurora Platinum Corp. (now FNX Mining) discovered 3 zones of high-grade Ni-Cu-PGE over a 7 km strike-length of the dike on claims east of the property. United Reef previously owned some of these claims and hold a 1% NSR.
