Ivanhoe Creek Exploration Model
There is a new, widely-accepted exploration model for the Midas, Ivanhoe, Rock Creek and Silver Cloud high-grade, vein-type, Low Sulfidation quartz-adularia gold-silver deposits in the Northern Nevada Rifts metallogenic province. The top of the high-grade ore zones, e.g. at Midas, formed at boiling horizons 350 to 400 meters below the paleo- ground surface (new NEM fluid inclusion data), and extend downward for variable distances.
The Midas Mine shows some of the world's best, with consistent head grades of 1.5 oz/ton Au and 12 oz/ton Ag, over a length of more than 1 kilometer, and this high grade lateral vein ore continuity may be a characteristic of the Midas District which distinguishes it from lesser quality vein mineral districts in the Western U.S.

Mercury rich but gold poor silica sinter layers were formed at the ground surface above these high grade deposits, along with local, discontinuous gold rich shoots above 350 meters where zones of flash boiling extended upward along fracture controlled fluid pipes, perhaps above an areal groundwater boiling interface. In the 1970s to 1990’s, exploration companies typically only looked for near surface (0 to 125 meters) open pitable, disseminated gold and silver deposits.
Kent Exploration has funded a C$600,000 diamond drill program and earned a 50% interest in Senator Mineral's option on the Ivanhoe Creek property.
Drilling commenced with hole DH-2 on May 4, 2007 with drill depths of between 100 - 350 meters.
