Orex Minerals (TSXV:REX) has announced the Phase-II diamond drilling program continues to intercept silver mineralzation on the Sandra Escobar Project i Mexico. Assays for five drill holes are available.
As quoted in the press release:
The Sandra Escobar Project is being advanced by Orex under an option agreement with Canasil Resources Inc. – (TSX.V: CLZ) (“Canasil”).
Highlight for this batch of holes is SA-16-019, which yielded 60 metres core length (49.2 m true thickness) grading 205 g/t silver, starting 16 metres vertically below surface. Within this is a sub-interval of 15 metres (12.3 m true thickness) grading 375 g/t silver.
Kluane Drilling Ltd. provides the drilling services utilizing an environmentally low-impact KD-1000 man-portable diamond drill rig.
Silver mineralization is hosted on the north side of a rhyolite volcanic dome. An altered and highly permeable volcaniclastic unit contains disseminations of silver bearing minerals and broadly spaced stockwork veinlets. The current working model has a porphyritic rhyolite unit as an impermeable cap, which may have focused mineralizing fluids into the host permeable volcaniclastic unit.
True thicknesses are estimated based on structural and stratigraphic interpretations. A map showing the locations of the drill holes and a sample cross section are available on the Orex website.
Orex maintains a QA/QC sampling protocol for the diamond drilling program, including the insertion of commercial analytical standards and blank samples. Analytical testing is performed by SGS Mineral Services. Silver values are determined by fire assay with a gravimetric finish. Multi-element analyses are also determined using a 4-acid digestion and ICP-MS (Inductively Coupled Plasma Mass Spectrometry).
