St. Elias Mines (CVE:SLI) unveiled Thursday drill results from its Tesoro gold project in southwestern Peru, intersecting gold at depths.
The company released the results of drill holes TE-12 to TE-35. So
far, 43 diamond drill holes for a total of 12,740 metres have been
completed, with assays pending for holes TE-36 to TE-40.
Drilling has tested a variety of targets, including geophysical, down
dip and along strike extensions of known gold-bearing quartz veins, and
coincident geophysical and geological targets.
St. Elias said Thursday that it has received inconclusive results
from drill holes that specifically targeted the geophysical anomalies
reported by Quantec, with Quantec data set to be independently examined
by Canadian geophysicists.
Despite this, drill holes that tested geological targets intersected gold at depths, the company added.
Indeed, holes with relatively deep intersections included hole TE-14,
which hit 7.08 grams per tonne (g/t) gold over 0.85 metres at a true
depth of 276 metres, and hole TE-29, which intersected 6.08 g/t gold
over an interval of 0.50 metres at 275 metres true depth.
The company said management is now planning a program of underground
exploration and bulk sampling of the gold-bearing structures intersected
during the surface drilling campaign.
St. Elias explained in a statement that the strategy is consistent
with the old gold mining rule of thumb, "drill for structure and drift
for grade," as high grade gold often occurs only in steeply-plunging
shoots in the plane of the vein.
One of the main aims of this program is to compare the grades and
widths of structures intersected by the drill holes with the "much
higher-quality data" obtained by bulk sampling the same structures
underground, St. Elias said.
At the end of May, the company also said it plans to temporarily
suspend drilling at the Tesoro project, "pending the receipt of the
independent evaluations of the existing geophysical data, completion of a
formal compilation of all available historic, geochemical, geological
and structural data, and detailed geological mapping covering a number
of historic mine areas."
The Tesoro gold project is 100 per cent owned by St. Elias, with no
underlying royalties. The property covers approximately 6,974 hectares
and lies within the 300 km by 30 km Nazca-Ocona gold province, which
trends northwest parallel to the Pacific coastline.
The belt is noted for the strike continuity of many of its quartz
vein systems and associated faults. While the veins are often narrow,
their gold grades can be high, especially in localized "shoots" that
occur where the vein geometries change.
The company has found five mineralized zones the Tesoro project that
host more than 50 quartz veins. Underground exploration and development
work has been carried out on three of these veins (C1, C2 and A4 veins).
A total of 1,157 tons of bulk sample material averaging 0.93 ounce
per ton gold has been extracted from the underground exploration and
development workings so far.
