Available assay results for eight of the nine drill holes that tested the Estrella gold prospect in the western Mexican state of Nayarit are much weaker than
The nine holes in 2,447 metres of diamond drilling tested the potential of an epithermal quartz vein/ stockwork brecciated zone. The gold zone strikes northwest and has been traced by geological mapping, as well as geochemical soil and rock sampling over a strike length of 1,500 metres.
Soil geochemistry results over the northern end of the Estrella alteration zone show a coinciding gold-silver anomaly. However, Valerie has found the gold values to be erratic when compared with the well-defined silver anomaly.
The drill holes explored an area measuring 600 metres along strike by 150 metres wide. Sections of low-grade mineralization were encountered in eight of the holes, with occasional, narrow high-grade intercepts.
The best intercepts were obtained in holes 1, 2 and 3 at the extreme northern end of the area tested. Hole 1 intersected 16.8 metres of 0.6 gram gold and 128.1 grams silver per tonne (including 2.16 metres of 2.28 grams gold and 513 grams silver), starting at 45 metres down-hole; hole 2 encountered 24.2 metres of 1.33 grams gold and 60.61 grams silver (including 2.2 metres of 6.73 grams gold and 26.59 grams silver) from a depth of 54.8 metres; whereas hole 3 cut 13.2 metres of 1.26 grams gold and 33.34 grams silver (including 1.75 metres of 4.45 grams gold and 57 grams silver) beginning down-hole at 29.6 metres.
Hole 3 was undercut 80 metes by hole 4, which yielded lower gold values across narrower widths, including 9.3 metres of 0.45 gram gold and 2.76 grams silver, from 92.5 metres of depth. The remaining holes, stepping out to the south, yielded narrow intervals of low-grade gold mineralization. Assay results have yet to be received for hole 7 but are expected to be consistent with the other holes.
