Millrock Announces Additional Drilling Results at Uncle Sam Gold Project, Alaska

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 09/01/11 -- Millrock Resources Inc. (TSX VENTURE: MRO) ('Millrock' or the 'Company') is pleased to report additional results from the first phase of drilling at the Uncle Sam gold project in the Tintina Gold Belt, Alaska. The project is located 65 km southeast of Fairbanks, Alaska, 60 km west of the Pogo Gold Mine and adjacent to a recent gold discovery reported by Sumitomo Metal Mining Co. Ltd. ('Sumitomo'). The work on Uncle Sam is being funded by Crescent Resources Corp. (TSX VENTURE: CRC) ('Crescent'); Millrock is managing the exploration. Crescent has an option to purchase a 100% interest in Millrock's rights to the property subject to a royalty. Millrock presently owns approximately 5% of the issued and outstanding common shares of Crescent.

Lone Tree Prospect

Five diamond drill holes totaling 1,329 m were completed by Millrock at the Lone Tree prospect located in the northwest part of the Uncle Sam property in 2011. Drilling targeted a 500 m by 250 m portion of a larger gold-in-soil anomaly measuring approximately 4,000 m by 1,000 m Previous historical drilling by other operators in the general area returned encouraging results such as drill holes USC-011, which contained an intersection of 19.22 m averaging 2.03 g/t gold and USC-013, which contained 6.0 m averaging 1.79 g/t gold and 14.0 m averaging 1.65 g/t gold. The drilling program was designed to expand upon the area of known gold mineralization. A summary of significant results follows:

The listed gold intercepts at Lone Tree typically occur within thicker zones containing anomalous gold mineralization commonly associated with faults and fault zones. This is evident in LT-005 which intersected 33.83 m grading 0.58 g/t gold. Host rocks for mineralization include both metamorphic rocks (schist, gneiss) and, to a lesser extent, granitic intrusive rocks. Because the rock cores are badly broken and faulted it is not possible to determine the true width of the intersections.

The Lone Tree area is one of three main previously defined areas of anomalous gold-in-soil occurring within the Uncle Sam project area (Lone Tree, Christmas, Wolf). Previous drilling in 2011 by Millrock at the Wolf Prospect, located approximately 3.5 km south of Lone Tree, encountered intercepts up to 11.40 m averaging 4.86 g/t gold was announced on July 28th, 2011 (http://millrockresources.com/news/millrock_announces_drilling_results_at_uncle_sam_gold_project_alaska/).

The Wolf Prospect appears to be on strike with Sumitomo's recently discovered Naosi mineralized zone (Stone Boy Project) located approximately 2 km to the southeast. Drilling by Sumitomo at Naosi has returned intercepts up to 7.92 m averaging 7.8 g/t gold and 19.7 g/t silver (http://www.petroleumnews.com/mnarch/05-23-1.html).

Additional Work

Millrock also completed a property-wide soil geochemical survey in 2011 designed to obtain data in areas not previously sampled. Results are pending.

Agreement

Signed in January of 2011, the agreement with Millrock gives Crescent the exclusive option to earn a 100% interest in the Uncle Sam claim group in return for a cumulative US$2.5 million in exploration expenditures, US$300,000 in cash payments and Crescent share issuances to Millrock. Crescent has issued 1,583,281 common shares to Millrock and these shares represent approximately 5% of the currently issued and outstanding Crescent shares. If the earn-in agreement proceeds to December 31, 2011, Crescent will issue to Millrock that number of common shares to give the Company 18% of the issued and outstanding shares of Crescent on that date. Millrock may be entitled to receive more Crescent shares in the event that an independently verified gold resource is defined on the property. Millrock obtained rights to the Uncle Sam property by virtue of an agreement with Kiska Metals Corporation (TSX VENTURE: KSK).
