Further drilling is in progress to discover extensions to the lower breccia high-grade
zone of mineralization and additional mineralization within the North Bullion target zone.
In a recent review of 371 patients who underwent surgery for high-grade
dysplasia, the incidence of occult cancer was 42%.
Although the pathologic diagnosis of low- and intermediate-grade mucoepidermoid carcinoma is relatively straightforward, high-grade
mucoepidermoid carcinoma can be difficult to differentiate from squamous cell carcinoma and therefore might require special histologic stains to demonstrate the mucous component.
resources at the Red Lake mine are estimated to be 484,000 tons at a grade of 2.
Frozen-section analysis identified these nodules as high-grade
Pau d'Arco (Brazil): This newly-acquired property in the Tapajos gold region has a history of high-grade
gold extraction from a mineralized zone by small-scale surface miners over a nearly continuous length of one-kilometer.
An early outcome of this geologic breakthrough was the identification of high-grade
gold-bearing veins on surface at the Santa Rita project where sampling by the Company returned surface grades of up to 118 g/t gold over vein widths of 1.
In particular, diamond drill hole D05-430 encountered several high-grade
mineralized structures including a downhole interval averaging 33.
In 2002, Apex Silver completed a Phase 1 exploration program and discovered several additional zones of silver-zinc-lead mineralization within the vein system at the Pulacayo Mine that are both broad and high-grade
More than half of the holes intersect and define the high-grade
gold deposit in the Discovery Area, which is at least 300 metres in length, 75 metres in width and 250 metres in depth.
Black Fox was acquired by Apollo in late 2002 during a period of depressed metal prices as part of a strategic plan for the Company to explore and develop high-grade
gold assets to replace its older and lower-grade producing properties.
