Millrock Provides Drilling Update from Council & Bluff Gold Projects in Alaska

VANCOUVER, BRITISH COLUMBIA, July 21, 2010 - Millrock Resources Inc. (MRO - TSX:V) ("Millrock" or the "Company") released today an update on its drilling of two gold projects in the Seward Peninsula of western Alaska, Council and Bluff. At the Council gold project, a joint venture with Kinross Gold Corporation ("Kinross"), with Millrock as operator, completed 2,062 metres of reverse circulation drilling to test for hardrock deposits in the historical placer mining region east of Nome, Alaska. The Millrock-Kinross joint venture at Council (for details click here) entails a large land package where over 300,000 ounces of past placer gold production have been recorded. Drilling was done at the Albion prospect, and on a large geochemical anomaly located on lands owned by the Bering Straits Native Corporation and Council Native Corporation.

Samples from the 17-hole Council drilling program have been shipped to Fairbanks Alaska for assay; preliminary XRF analysis indicated numerous intercepts with anomalous gold pathfinder elements of arsenic and antimony. A supplemental geological mapping, prospecting and geochemical program designed to identify additional targets for 2011 drilling has been authorized by Kinross. Rock chip samples collected during the reverse circulation drilling program will be compiled as they are received from the laboratory over the coming weeks. It is anticipated that all results will be in hand and ready for publication in late August or early September.

At the Bluff gold project, a joint venture with Valdez Gold Inc. ("Valdez"), initial drilling by the partners, with Millrock as operator, is scheduled to begin July 23rd. Approximately 4,500 metres of reverse circulation drilling is planned as part of a US$1.2 million 2010 exploration budget. Valdez can earn up to a maximum 75% interest in Bluff with expenditures of US$6 million in exploration, US$900,000 in option payments and share issuance of two million Valdez shares (for details see here).

The Bluff property is comprised of a land tract covering a total 142 sq km approximately 80 km east of the town of Nome and 24 km east of the Big Hurrah gold deposit, which NovaGold is considering for production and processing at the Rock Creek Mine. The land is owned by the Bering Straits Native Corporation and the White Mountain Native Corporation. Millrock and Valdez have an option to lease the lands for mining.

At Bluff, structurally controlled gold mineralization occurs within a 6.4 km long, arcuate band of schistose rocks near a contact with marble. Drilling by BHP Billiton Ltd. ("BHP") in the late 1980s identified three zones of mineralization. The zones contain several significant intersections including 5.48 g/t gold over 10.9 meters, 4.19 g/t gold over 4.5 meters, and 1.93 g/t gold over 16.3 meters.

Millrock explored the property in 2008 with geological mapping and soil sampling identifying new zones of mineralization and high priority drill targets. Drilling and resampling of BHP core confirmed the presence of gold mineralization. Significant drilling is required on all zones to establish and delineate gold resources. There are numerous drill targets adjacent and down-dip from known gold zones and untested surface geochemical anomalies.
