Radius moves rig to Sastre

Vancouver With the first seven reverse-circulation drill holes cutting low-grade gold mineralization in a carbonaceous phyllite unit at the Lupita target, Radius Explorations (RDU-V) has moved the rig over to the Sastre zone on the Tambor project in Guatemala.

Two of the final three holes collared at Lupita bottomed in mineralization.

Hole 6 hit 18.3 metres grading 1.39 grams gold per tonne from 115.8 metres down-hole.

Hole 7, which was collared 200 metres west of hole 4 (135.6 metres averaging 1.22 grams gold), returned 149.3 metres grading 0.77 gram gold from surface.

Hole 5 failed to penetrate the rocks above the favourable phyllite unit.

So far, hand trenching and drilling have outlined a zone of mineralization measuring 400 metres by 400 metres. A newly built drill access road uncovered mineralized carbonaceous phyllite some 500 metres west of hole 7, indicating that the zone remains open along strike and at depth.

The junior also twinned hole 4 with a core hole to confirm the grade distribution and test the depth extent if the zone. The hole was lost at 90.5 metres due to poor ground conditions. Assay results are pending.

Lupita is the most easterly of several targets to be tested. The gold mineralization occurs in a carbonaceous phyllite unit in association with strong multi-stage hydrothermal quartz veining containing disseminated pyrite and arsenopyrite. A hangingwall amphibolite schist, sitting at the top, was unmineralized. One drill hole also cut the footwall, which was also amphibolite schist.

Based on the drilling, Radius believes the phyllites have been sliced into the amphibolite schist along a fault zone. The mineralized zone is dipping about 10 to the west. The oxidized mineralization exposed in the trenches is now believed to be just a thin skin, or rind, on surface. The mineralization intercepted in the drilling consisted entirely of sulphides.

The favourable phyllite horizon can be traced from Lupita for a distance of 4 km west to the Bridge zone, where it disappears under volcanic ash cover. For much of this distance, its inferred subcrop coincides with a gold-in-soil anomaly. Samples from scattered outcrops and hand trenches within the anomaly yielded values in excess of 1 gram. Previous channel sampling at the Bridge zone returned 85 metres grading 3.59 grams.

The reverse-circulation drill rig is at the Sastre zone and will test the downdip extension of surface mineralization hit in trenches with six holes.

The Tambor property occurs in a new belt of rocks, which has now been traced over a distance of more than 20 km. Regional work in the past 18 months has uncovered three large gold anomalies in this belt.

Ten individual prospects have been identified, all of which will be eventually drilled.
