Helio Resource (HRC-V) has received some interesting results after testing the Porcupine target at its SMP gold project in Tanzania from a new angle.
Up until recently, all drilling at Porcupine has basically been perpendicular to the surface but the last three diamond drill holes were drilled from a different orientation.
All three holes cut through the main mineralized zone and many of the structures in the oriented drill core were at a high-angle to the core axis, Helios reports. The company has included a diagram on its website.
Helios says these results demonstrate the potential for Porcupine to host some variably oriented mineralized structures and the company plans to continue doing structural interpretation and targeting of these structural intersections.
Drill hole GDP 63 intersected 52 metres grading 1.7 grams gold per tonne starting at 32 metres depth.
GDP 64 returned 47 metres grading 2 grams gold per tonne starting at 118 metres depth.
And GDP 65 returned 52 metres grading 3.7 grams gold per tonne from 203 metres depth (uncut) including 1 metre grading 98.9 grams gold per tonne between 208 and 209 metres.
(When a cutoff grade of 31 grams gold per tonne is used for GDP 65 the intercept is 52 metres grading 2.4 grams gold per tonne.)
Helios says a new mineralized zone was intersected in this hole – 10 metres grading 5.8 grams gold per tonne from 303 metres depth.
The SMP project is located on a 238-sq.-km land package in the Lupa Goldfield of southwestern Tanzania.
Helio plans to drill 30,000 metres there this year using one diamond drill and two reverse-circulation drills.
The diamond drill is being used on the Porcupine target testing strike extensions and structural controls to higher-grade mineralization.
With the RC rigs, Helios is testing new targets that were identified in a magnetic survey conducted in late 2009.
Porcupine has been drill-tested over a 450 metre strike length, and from surface to a vertical depth of below 300 metres. Helios says mineralization is open to the east, west and at depth.
Gold mineralization at Porcupine is associated with multiple sheeted quartz veins within a structural zone that ranges up to 90 metres wide.
The other targets at the SMP gold project are known as the Kenge and Tumbili zones.
