Rox re-sampling confirms mineralised zone at Teena

/in /by

THE DRILL SERGEANT: Rox Resources (ASX:RXL) has completed re-sampling of two historic drill holes from the recently-identified Teena zinc prospect, located on the company’s Myrtle/Reward zinc project in the Northern Territory.

Rox claims the results have confirmed Teena as a medium to high-grade zone of mineralisation.

“The re-sampling results, from holes Teena 4 and 6, confirm a close comparison between the historic drill core assays and the samples re-assayed by earn-in partner, Teck Australia,” Rox Resources said in its ASX announcement.

“Due to the heavily degraded nature of the drill core, being 35 years old, complete re-sampling on a metre by metre basis could not be undertaken.

“Instead, Teck selected samples within the mineralisation in one hole randomly and at various regular intervals in the other hole.”

According to Rox, the historical assays when compared against the re-sampled assays demonstrate no material differences.

There is a slightly higher anomalous grade in the zinc re-assays, while lead has a slightly higher anomalous grade in the historic assays, particularly at lower levels.

The mineralised intersections at the Teena prospect were drilled between 1976 and 1978 by Mount Isa Mines.

At Teena, significant zinc-lead-silver mineralisation was intersected in a number of widely spaced drill holes.

The best results included:

–    11.3 metres at 10.9 per cent zinc and lead, 14 grams per tonne silver from 908.8m in hole Teena 4;

–    8.6m at 9.84 per cent zinc and lead, 23g/t silver from 789.6m in hole Teena 4A;

–    3.8m at 7.98 per cent zinc and lead, 4g/t silver from 629.2m in hole Teena 2; and

–    13.1m at 6.02 per cent zinc and lead, 5g/t silver from 599.2min hole Teena 6.

Rox said the drill data show potential for a large zone of high-grade zinc-lead mineralisation over an area of at least one kilometre by 1.5 kilometres and cumulative thickness of between five metres and 40m.

The company indicated it has further exploration at Teena planned for the December quarter including surface geochemical sampling.

Drilling to confirm the grades and thicknesses is expected to occur early in the 2013 field season, which the company anticipates will establish Teena as a significant zinc-lead prospect within the Myrtle/Reward project.
