Dark Horse Resources confirms widespread gold and silver at Las Openas

Dark Horse Resources (ASX: DHR) has confirmed widespread gold and silver mineralisation at its Las Openas gold project, with channel sampling unearthing up to 54.2 grams per tonne gold and 739g/t silver.

The mineralisation was identified from 34 channel samples that were cut over 2km of strike at the Presagio zone, with nine samples excavated from the Vultur zone.

Of the samples, 17 assayed above 1g/t gold, with five grading above 5g/t gold.

Best assays with the highest gold grades were 0.4m at 54.2g/t gold and 83g/t silver, 0.8m at 17.9g/t gold and 225g/t silver, and 0.7m at 10.4g/t gold and 263g/t silver.

Meanwhile, the highest-grade silver sample was 0.8m at 0.55g/t gold and 738.9g/t silver.

Zinc, lead, copper, molybdenum and manganese mineralisation were also present at varying grades in the majority of samples.

According to Dark Horse, the channel sampling program followed a first phase drilling campaign which uncovered five mineralised vein systems at Openas, with Presagio the most promising target.

Dark Horse plans to use the sampling results along with its mapping data to plan another drilling program, which is scheduled to begin in the December quarter.

Las Openas gold project

Located in Argentina, Openas borders the Indio Belt which hosts numerous multi-million ounce gold deposits.

Highlight results from the initial 17-hole drilling program undertaken in the March quarter were 3m at 4.75g/t gold and 54.9g/t silver and 1m at 4.84g/t gold and 349g/t silver.

Dark Horse entered an agreement to acquire Openas in January this year from Genesis Minerals (Argentina) SA.

The agreement allows for Dark Horse to acquire 100% of Openas over a 3.5-year staged earn-in, with the total amount payable being US$880,000 and 90 million Dark Horse shares.

Zinc miner Teck Resources previously explored the 1,462 hectare property between 2005 and 2012.

The market reacted positively to Dark Horse’s exploration news, with the company’s share price soaring more than 66% to reach $0.005 by mid-morning trade.
