About Black Widow

Black Widow was incorporated under the laws of Canada, pursuant to the Canada Business Corporations Act in January, 2011. Its registered office is located at 65 Front Street East, Suite 304, Toronto, Ontario, M5E 1B5.

Black Widow is a privately-held exploration and development company focused on identifying and exploring precious and base metal properties.

Black Widow holds a 75% interest in 29 claims (464 units, or 7,424 hectares), with the option to acquire a further 25% until May 2012. The property, known as the Gremlin Project, is located approximately 25 kilometers north of the Ring of Fire area in the James Bay lowlands of Northern Ontario. Black Widow has recently completed a high definition four sensor tri-axial array low altitude helicopter borne-mag survey over the property at an approximate cost of $80,000, follow up ground work is currently being planned for early 2012 to meet the expenditure requirements to earn the final 25% interest in the property and to meet assessment work requirements. A preliminary review of the new airborne data reveals two very promising areas covering 4 distinct anomalies for immediate ground follow-up in a program of line cutting and HLEM geophysical surveying for drill hole siting purposes. The recent airborne survey enhanced the anomalous responses first observed in a 2005 VTEM survey flown by former property operators, results of which were never followed up. Black Widow plans on incurring approximately $250,000 in exploration expenditures on this project by July 2012 and to exercise the final earn-in obligations to vest a 100% interest in the property, prior to drill testing the project.

Black Widow has an option to acquire a 70% interest in the Santa Maria gold project, optioned from United Reef. The Santa Maria project consists of 19 unpatented mining claims (87 units, or 1,392 hectares) located 45 kilometers southeast of Dryden, Ontario. The Santa Maria property includes at least 6 known gold occurrences, with gold values ranging from trace to 28 g/t, documented on the property, visible gold has been observed in 3 of these zones. The Santa Maria shaft zone was explored by shallow vertical shafts in the early 1900's. Black Widow can acquire a 70% interest in project by expending $90,000 prior to May 2012 after which a joint venture will be formed with United Reef. Black Widow will be completing an airborne VTEM geophysical survey on the property during December 2011, at an estimated cost of $65,000, partially fulfilling the earn-in requirement of the option.

Black Widow is currently negotiating interests in other projects in Ontario and elsewhere.

United Reef is a company incorporated under the laws of the province of Ontario. Its registered office is located at 120 Eglinton Avenue East, Suite 1000, Toronto, Ontario, M4P 1E2.


Santa Maria Gold Property - Dryden area

United Reef holds a 100% interest in the Santa Maria gold project located within the Eagle-Wabigoon-Manitou Lakes Greenstone belt near Dryden, in northwestern Ontario. This property is subject to an option earn-in agreement with Black Widow, whereby Black Widow can earn up to a 70% interest in the property by incurring no less than $90,000 in exploration expenditures prior to May 2012 (see United Reef press release dated November 15, 2011). The property consists of 19 contiguous unpatented mining claims comprising 87 claim units encompassing an area of approximately 1,392 hectares. The Santa Maria property is host to several known gold occurrences where gold values ranging from trace to 0.82 oz/ton (28.0 g/t) have been documented from the property, visible gold has been observed in at least 3 of these zones. The Santa Maria Shaft Zone was explored by two shallow shafts in the early 1900s. The property covers a series of strongly developed, deeply seated east-west structures that lie along the north flank of a major northwest trending fault zone. These structural features are indicated on OGS geological maps of the area, satellite imagery and field observations. The property also hosts intense carbonate alteration and numerous quartz zones.


Nickel Offsets Property - Sudbury area

United Reef granted to URSA Major Minerals Inc. an option in March 2008 (as amended) to earn a 70% interest in the Nickel Offsets property by incurring $1.25 million in exploration expenditures over a 4 year period (ending in March 2012). In the fall of 2009, URSA Major completed diamond drilling and down-hole geophysics on the property and identified new massive sulphide targets in proximity to the existing mine workings. These encouraging results were followed up by a fall 2010 drilling program. Highlights from that program include an intersection of 2.89 metres of nickel rich massive sulphides (2.90% nickel, 0.97% copper, 0.16% cobalt, 0.94 g/t platinum, 1.28 g/t palladium, and 0.11 g/t gold) and 2 meters of platinum group metal mineralization (3.04 g/t platinum, 2.00 g/t palladium, 0.82 g/t gold, with 0.07% nickel and 0.37% copper) in disseminated sulphides in the footwall of the nickel-rich massive sulphides. URSA Major is currently planning a third drilling phase to be completed in late 2011 or early 2012. The property consists of 12 patented and 5 unpatented mineral claims totalling 357 hectares covering 2.3 kilometers strike of the Foy Offset dike. The property includes the past-producing Nickel Offsets Mine (1943-1957) and historic records indicate extensions of mined ore lenses may remain in place. Once URSA Major completes the earn-in of 70%, United Reef can contribute to a joint venture program and maintain its 30% interest or undergo dilution.
