VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 11, 2011) - CARIBOU COPPER RESOURCES LTD. ("Caribou Copper" or the "Company") (News - Market indicators) announces that it has entered into an agreement with Alix Resources Corp. (TSX VENTURE:AIX) to earn-in on five prospective properties located in the Yukon. The five properties consist of the Hartless Joe, Byng, Corky, Meloy and Vault, which are optioned by Alix from Strategic Metals Ltd. (see Alix news release dated January 31, 2011). Work programs on at least three of these properties are anticipated to commence within the next four weeks.
The Hartless Joe and Byng properties are 28 and 44 kilometers northeast of Whitehorse, respectively and both host low sulfidation epithermal gold-silver vein systems developed in mafic and felsic volcanics and associated sedimentary rocks of the Stikine Terrane. Previous grab sampling from mineralized veins conducted on behalf of ATAC Resources Ltd. in 2004 returned grades of 0.8 to 251 g/t (grams per tonne) gold and from 13.5 to 5,780 g/t silver. Hartless Joe totals 1,000 hectares under claim and features numerous undrilled soil geochemical and geophysical targets. Byng has 405 hectares under claim, and it also features several geochemical anomalies that have not been tested by drilling.
Corky is located 125 kilometers northwest, and Meloy is located 80 kilometers north-northwest, of the community of Haines Junction. Both are copper-gold prospects with potential molybdenum (Corky) and tungsten (Meloy) credits. They are both porphyry targets associated with high level granitic intrusions. The 750 hectare Corky property has seen limited geophysical surveys and drilling, with eight drill holes totaling only 800 meters. Meloy covers 850 hectares, and has not been drill tested. Both properties warrant detailed soil geochemical sampling and geophysical surveys to define targets for drill testing.
Vault is another gold prospect, located 140 kilometers northwest of Haines Junction. It covers 3,650 hectares in Wrangellia Terrane. The Vault property hosts numerous high gold (200 ppb to over 10,000 ppb Au) soil anomalies, the distribution of which suggests that the source could be a stacked sequence of thrust faults cutting Permo-Triassic metasedimentary rocks over 12 kilometers of strike length. No detailed geophysical surveys or drilling have been carried out on the Vault property.
To earn a 49% interest in the five properties, Caribou will issue 500,000 common shares and pay $50,000 cash to Alix and spend $600,000 on the properties over two years. Once the joint venture is established, Caribou will share its proportionate amount of the underlying agreement with Strategic Metals Ltd. on these five properties. The underlying agreement calls for cash payments totaling $2,900,000 cash over a four year period. To date, Alix has paid $100,000 and has issued 1,542,470 shares to Strategic Metals Ltd. Upon earn-in with Strategic Metals Ltd., the properties will be subject to a 2% net smelter return royalty. Alix and Caribou will have the option to buy back 1% for $1,000,000.
