The 100% owned Moonlight Project is located 200 kilometres northeast of Reno, Nevada and is comprised of over 13 sq miles (35 sq kms). Moonlight is approximately 8 kilometres north of the Coeur d'Alene Rochester silver-gold mine. The Rochester Mine has produced over 125,000,000 ounces of silver and 1,200,000 ounces of gold in its 25 year history and has recently returned to production. Additionally, the Moonlight Property adjoins, on the north side, the Barrick Gold Corp. / Midway Gold Corp. joint venture of the Spring Valley Project (Spring Valley is between Terraco and Coeur Rochester). The Spring Valley project, operated by Barrick, has announced a NI 43-101 resource of 4,100,000 ounces of gold. Barrick's drilling confirms the gold mineralization is open to the north (towards Moonlight) and at depth.
The Moonlight project area was identified and the initial claims were staked by Cordilleran Exploration Company ("Cordex"), on behalf of Metallic Ventures (U.S.) Inc ("Metallic") in 2004. Terraco entered into their original Exploration Agreement with Metallic in March of 2006. TCG Holdings, Ltd., a wholly owned subsidiary of Terraco Gold Corp, via a Purchase Agreement with Metallic Ventures (U.S.), Inc., acquired 100% of the rights to the Moonlight Project in June, 2007. Additionally, the underlying royalty position held by Cordilleran Exploration ("Cordex") was also purchased at the same time. The Cordex principals are John Livermore, who is credited with the discovery of the Carlin deposit in Nevada and the discovery and development of the Pinson and Dee mines, and Andy Wallace, who is credited with a major role in the discoveries of the Marigold and Stonehouse/Lone Tree gold deposits as well as the Daisy (Secret Pass) mine.
The Moonlight property, in the central part of the Humboldt Range northeast of Lovelock, is underlain by a Late Paleozoic to Early Mesozoic sequence of intermediate to felsic metavolcanic rocks known to host nearby, significant silver and gold deposits and prospects. These include the Coeur Rochester mine, which has produced 125 million ounces of silver and 1.2 million ounces gold to date, and the Spring Valley gold prospect which is currently the focus of a major exploration & development program by Barrick. These and other mineral properties and deposits in the central part of the Humboldt Range are spatially related to a regional-scale structural system that extends through the Moonlight property.
Spring Valley was a blind discovery beneath significant thicknesses of alluvium within an intermontane basin.
The central part of the Moonlight property features a similar alluvium-filled basin marginal to which are two precious metals prospects including Moonlight mine which was reportedly one of Nevada's highest grade silver producers (NBM&G Bulletin 89, 1977, M Johnson, pg. 61).
Midway Gold's NI 43-101 Technical Report for Spring valley, dated 25 March 2009, states: "The Spring Valley deposit is hosted in bimodal volcanic rocks of the Permo-Triassic Koipato Group. The deposit is aligned along the Black Ridge fault which is a steeply dipping, normal fault. The Rochester and Nevada-Packard Silver-Gold Mines and the Relief Canyon Gold Mine are also found along this fault. MGC has defined a zone of mineralization that is 5,000 feet long, 2,500 feet wide, and extends to a known depth of 1,400 feet. Known mineralization remains open to the north, southwest, and at depth."
Gold and silver mineralization are known to be controlled by northerly-trending structures at Moonlight. Current evidence suggests that the Black Ridge Fault Zone is a complex structural zone, estimated to be locally greater than 1,000 feet wide, whose eastern boundary controls the eastern margin of precious metals mineralization at Rochester and Spring Valley. Mapping at Moonlight indicates that this district-scale fault system continues northward through the Moonlight Project properties. An aero-magnetic survey conducted in 2006 supports this conclusion.
To date, Terraco has completed an aero-magnetic survey of the project area, collected and analyzed more than 400 rock samples, and drilled over 40 reverse-circulation drill holes ranging in depth from 400 to 800 feet, partially tested only a few of the target areas.
