VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sep 19, 2012) - Millrock Resources Inc. (TSX VENTURE:MRO) ("Millrock" or the "Company") announced today that it has generated a new copper-gold project named Stellar. The project is located in central Alaska 13 km north of the Denali Highway and 68 km west of the town of Paxson. The property, which was acquired by staking, covers the Zackly copper-gold skarn deposit and surrounding lands considered prospective for porphyry copper-gold deposits. At Zackly, a historical resource of 218,944 ounces of gold and 66.9 million pounds of copper contained in a deposit of 1,244,000 tons (1,128,500 tonnes) grading 0.176 ounces per ton (6.03 grams per tonne) gold and 2.69 % copper has been reported by prior explorers (UNC Teton Exploration and Drilling Inc., 1982). (Note:A qualified person has not done sufficient work to classify the historical estimate as current mineral resources. The issuer is not treating the historical estimate as current mineral resources).
Philip St. George, Millrock Chief Exploration Officer, stated: "We feel that the skarn resource can be readily expanded. The favourable limestone-diorite contact can be traced hundreds of meters along strike in both directions from the resource area, and with the exception of the "main skarn zone", has had limited drilling. Additionally, there are indications that the gold grade may be significantly under-reported. Outside of the previously defined skarn zones, we feel the project has significant potential for the discovery of a large copper-gold porphyry system. Our exploration crews have discovered porphyry mineralization at surface that has not been drill tested and Millrock soil sampling has extended anomalous zones substantially."
The Zackly skarn was originally staked by Resource Associates of Alaska (RAA) in the 1970s with the majority of exploration campaigns occurring between 1981 and 1994. The most extensive exploration programs were conducted as part of several joint ventures between RAA/Nerco and Teton Exploration Drilling, Boulder Gold, Phelps Dodge and Hemlo Gold/Noranda. Historical diamond and reverse circulation drilling on the skarn prospect totals approximately 40,000 ft (12,192 m) in approximately 85 holes. Known areas of skarn mineralization occur over a strike length in excess of three km with the known resource occurring within the "main skarn zone" which has a strike length of approximately one km. The majority of the historical drilling occurred in the "main skarn zone" with the remaining trend, which includes extensive covered areas, seeing only limited drilling. In addition to drilling, the property has seen extensive geochemical, geophysical and geological surveys. All historical data, as well as sample pulps and core, were recently obtained by Millrock in a purchase agreement. Presently the Company is digitizing the information and bringing drill hole logs and analytical data into its Geographic Information System.
Millrock began staking claims in the area in 2010, subsequently adding claims in early 2011 and finally in August of this year bringing the total project area to an approximate 30,500 hectares (see figure here: http://millrockresources.com/projects/stellar/). Since 2010, Millrock has collected 388 soil, 199 rock and 99 stream sediment samples throughout the project area resulting in the discovery of at least four new copper and/or gold prospects. Of particular note is the Mars prospect, located approximately 10 km west of Zackly. This prospect consists of altered diorite intruding volcanic rocks with extensive gossan exposures that locally contain copper mineralization. Soil sample lines across altered zones consistently returned anomalous values including 950 meters averaging 763 ppm copper and 1.2 kilometers averaging 462 ppm copper.
Millrock considers the Stellar Project a highly prospective property with excellent exploration potential for the discovery of significant porphyry copper/gold, skarn and intrusive-related gold mineralization. Millrock, which has 100% ownership of the project subject to a royalty to Altius Minerals, is currently seeking a joint venture partner for the project. Additional information on the Stellar Project, as well as all of Millrock''s available properties is available at the Millrock Resources website (www.millrockresources.com).
