A widely spaced, 16-hole program of reverse-circulation drilling has confirmed the continuity of the main mineralized shear zone at the Santa Helena property in Brazil.
Owner Black Swan Gold Mines (TSE) conducted the initial, 1,192-metre program in order to test the steeply dipping, northeasterly trending structure over a strike length of 600 metres. The drilling was carried out at an angle of minus 60.
During the past five years, local miners worked oxidized surface gold showings to maximum depths of 10 metres, at which the sulphide nature of the gold mineralization hampered any further mining at depth.
Grab sampling of waste piles and tailings returned peak gold values of 74.03 and 48.8 grams per tonne, respectively. Black Swan believes that together with a high-grade drill intercept from hole 5, grading 18.45 grams over 1 metre, high-grade ore shoots exist in the shear zones.
Significant drill results are as follows:
