paris hills phosphate

Geology
The chart to the right shows the expected upper and lower phosphate zones within the Paris Hills project area. The geological horizon of interest is within the Phosphoria Formation. At the bottom of the Meade Peak, is a lower phosphate bed ranging in thickness from 6.5 to 23 feet. The vanadium rich bed that lies between the upper and lower phosphate zones is approximately 11 feet thick. The upper phosphate bed is approximately 15 feet thick. Both the upper and lower phosphate zones contain 23% to 28% phosphate. There is 170 feet of waste shale between the lower phosphate bed and the vanadium.

Mineralization/Deposit Type
The Paleozoic rocks have been formed into an asymmetrical syncline beneath the west-dipping Bannock thrust fault. The phosphate and vanadium rich beds in the western limb of the syncline outcrop and can be traced over three miles along the surface.

The phosphate and vanadium rich beds in the east limb are exposed along the surface about one mile before they are covered by valley fill and are mostly displaced by range front faults. The north plunge of the syncline has gradually increased the depth of the phosphate and vanadium beds in the east limb of the syncline so that they are approximately 2,500 feet below the surface at Paris Canyon and 3,300 feet deep beneath the surface at the northern edges of prospect area.

Drilling has confirmed the presence of the syncline and has located several faults with 20 to150 feet of displacement of the sedimentary beds. These faults may occur as close as every 200 – 300 feet but generally are spaced at about 500 feet. The spacing and displacement of the faults can be catered for in the underground mining methods contemplated.
