TORONTO, July 15, 2013 (GLOBE NEWSWIRE) -- Strata Minerals Inc. (TSX-V:SMP) ("Strata" or the "Company") is pleased to announce final results and conclusions from the Company's Phase 1 exploration program at its 80% owned Cardabia Phosphate Project ("Cardabia") located near Exmouth in Western Australia.
Strata's key findings from the Phase 1 program of exploration drilling and preliminary metallurgical test work at Cardabia are summarized as follows:
- Drill hole results consistently demonstrate the presence of a shallow sedimentary unit hosting P 2O 5 within mineralized zones totaling approximately 0.5 - 2.0 meters in thickness, with an average thickness of 1.0 meters;
- The unit is observed to reach its easterly extent and outcrop along a northeast-southwest trend of some 21 km in the southeastern section of the Cardabia tenements, and dips gently to the north-west;
- In head grade samples with sufficient mass to the +1mm fraction, the coarse material averaged 19.9% P 2O 5 with a starting head grade average of 1.8%;
- The phosphate mineral is concentrated in the form of apatite and does not appear to be entrained with waste minerals; and,
- Combined Fe 2O 3 and Al 2O 3 assay results in samples analyzed were high, but are potentially manageable in a conventional flotation process. Testing indicated that U 3O 8 concentrates in the coarse fractions; however, on average, the levels are well below currently accepted limits.
