Arc Exploration shares surge on drill results from Trenggalek gold prospect

Arc Exploration (ASX: ARX) has announced further encouraging drill results from its scout drilling programme at Trenggalek in East Java.

On 12 March ARX announced positive drill results from the first two holes (TRDD 1 and 2) drilled at Trenggalek. Since that time results of a further three holes have been received.

These latest holes, TRDD 3, 4 and 5, all located in the southern portion of the West Sentul Vein, total 295 metres.

All three holes returned narrow high grade gold (8-17 g/t Au) intersections from within broader moderate grade gold (4-6 g/t Au) zones hosted in the vein.

TRDD 4 and 5 were drilled perpendicular to the vein on the same section as TRDD 2 to test vein continuity to a depth of approximately 150 metres below surface.

TRDD 3 was drilled to the north from this section to intersect the vein at about the same elevation as TRDD 2 but approximately 25 metres further north along its strike.

Total reported meterage to-date is 550 metres or just over 10% of the 5,000 metre programme to be conducted this year to test and rank several prospects for further drilling.

TRDD 3 returned two separate 1 m intersections of 10.4 g/t Au & 21 g/t Ag and 10.2 g/t Au & 40 g/t Ag within a 9.4 m intersection of 5.27 g/t Au & 18 g/t Ag from 35.1 m down-hole.

TRDD 4 returned a 2 m intersection of 17.2 g/t Au & 13 g/t Ag within a 9.65 m intersection of 4.51 g/t Au & 8 g/t Ag from 111.35 m down-hole.

It also returned a separate 1 m intersection of 7.34 g/t Au & 10 g/t Ag within a 10.75 m intersection of 3.62 g/t Au & 9 g/t Ag from 127.95 m down-hole.

TRDD 5 returned a 1 m intersection of 8.10 g/t Au & 23 g/t Ag within a 9 m intersection of 4.91 g/t Au & 19 g/t Ag from 5.8 m down-hole.

The true-width of the mineralised vein in this part of the vein system appears to be consistent at approximately 6-7 metres.

The Company regards these results as very encouraging as they confirm the occurrence of high grade gold mineralisation surrounded by moderate grade gold mineralisation to a depth of at least 150 metres below surface in the southern part of the West Sentul Vein.

Mineralisation is open in both directions along strike and at depth. The vein textures observed in these recent intercepts are considered to be typical of strongly mineralised, high-level epithermal gold-vein systems described elsewhere in the Indonesian archipelago.

Arc Exploration shares rose 20% to 4 cents in trading this morning.
