Anyone know what high grade phosphate P2O5, over 30%, 50%?
Thanks

Pacific Ridge Exploration (PEX-V) successful land acquisition and initial exploration programs in 2008 have defined attractive phosphate mineralization at numerous locations within a cumulative 127 kilometres of length of favourable geologic setting. The 517-square-kilometre Tumbler Ridge property is located in east-central British Columbia.
The 2008 exploration program has identified widespread sedimentary or "blanket-type" and laterally continuous phosphate mineralization. Of particular note are the Wapiti and Tunnel zones which yielded values to 29.1 per cent P2O5 over three metres and 19.4 per cent P2O5 over three metres respectively. The exploration program also outlined five additional targets where thicker and higher grade zones of phosphate are exposed. Although the early stage Tumbler Ridge project has only seen its first year of exploration drill-ready targets directed to tonnage and grade definition have been selected.
Exploration targets
Wapiti zone
The drill-ready Wapiti zone, located within the southern portion of the property, consists of an 18-kilometre-long exposed phosphate-bearing strata with higher than average grade mineralization. Pacific Ridge sampled and trenched a 4.9-kilometre-long portion of the 18-kilometre zone with trench values reaching to 29.1 per cent P2O5 over three metres. In several locations, the phosphate horizon occurs as dip-sloping beds suggesting opportunity for open pit extraction.
As previously announced, Wapiti is held under option from Lateegra Gold Corp. wherein Pacific Ridge may earn up to a 65-per-cent interest by making prescribed payments and expenditures over a five-year period.
Tunnel zone
The 100-per-cent-owned Tunnel zone, located in the northern portion of the property, covers a 900-metre length of the regional phosphate horizon where seven trenches excavated across the zone and spaced roughly equidistant along the 900-metres length of mineralization, averaged 16.1 per cent P2O5 over 3.6 metres. Opportunity for definition of near-surface large tonnages occurs within areas of dip-sloping mineralization. The Tunnel zone warrants drill testing.
Additional zones
Initial exploration has also discovered five additional phosphate targets -- Muinok, Mount Palsson, Meosin, Hook Lake and Windy Camp -- within the 127-kilometre-long property. Initial sampling yielded assay values to 26.4 per cent P2O5 suggesting potential for defining multiple areas of phosphate mineralization. Continued exploration to define future drill targets is warranted.
Location
Tumbler Ridge phosphate is located near the communities of Tumbler Ridge and Dawson Creek. Located within close proximity to, rail power and road access play an important role in determining positive economics for potential future production.
General phosphate information
Phosphate is one of several key components for generation of fertilizers used globally in the agriculture industry as well as the production of industrial supplies, pharmaceutical products and battery technology development. Phosphate mineralization is mined and then concentrated to phosphate rock, from which phosphoric acid (SPA) is an end product. Recent contract sales of SPA, grading in the range of 70 per cent P2O5, had pricing over $800 per tonne.
Pacific Ridge's disclosure of a technical or scientific nature has been reviewed by Wayne J. Roberts, PGeo, vice-president, exploration, of Pacific Ridge and a qualified person under the definition of National Instrument 43-101. |
