Goldrush Resources (CVE:GOD)(OTCQX:GDRRF) Wednesday confirmed the presence of prospective targets for follow-up exploration at its 44-square kilometre Ouavousse permit in central Burkina Faso, West Africa.
The targets were discovered after recent investigations including mapping, rock sampling and structural interpretation at four previously identified gold-bearing areas at Ouavousse.
A 2,800-metre reverse circulation drilling program was started at Ouavousse on Monday.
Goldrush president and CEO, Len Brownlie, said: "The decision to immediately drill several highly prospective targets on Ouavousse comes as a direct result of recent site visits conducted by Goldrush exploration staff who have collected rock samples with favourable gold values from well established artisanal mining sites.
"On our most recent visit on November 24, we observed over 250 artisanal workers mining gold bearing quartz veins that appear to have significant size potential. This combination of favourable geology, structure and apparent width and strike length have caused us to accelerate exploration of this permit.
"Our exploration team, led by chief geologist John Learn and vice president Driff Cameron have been exceptionally busy and will have organized drill programs totaling 23,000 metres on six Goldrush permits during the fall 2011 drilling campaign. All of these programs will be completed by year-end and assay results from these programs will provide a steady flow of news into the new year."
The Ouavousse permit is immediately west of, and crossed in part, by the interpreted corridor of the Markoye Fault, a major north-northeast trending structural zone and possible Porcupine-Destor Fault analogue, which has been traced for over 400 kilometres in Burkina Faso.
A number of substantial gold deposits, two of which have been brought into production - Taparko in 2007 and Essakane in 2010 - are associated with the Markoye corridor, as are other deposits and occurrences.
Goldrush said that the main Ouavousse and OTR-1 trench areas, where the company encountered 1.58 grams per tonne (g/t) gold over 5 metres in 2007, occur immediately adjacent to the Markoye Fault on related oblique structures.
A 300-metre long artisanal mining site has developed within the last two years at the OTR-1 site, as well as two main artisanal site trends of 400 metres (North trend) and 600 metres (South trend), located 700 metres on strike to the southwest.
The total potential strike length of this structure appears to be at least 1,700 metres.
The North trend provided eight grab samples, which ranged as high as 7.13 grams per tonne (g/t) of gold and averaged 3.02 g/t gold. Ten samples from the auriferous South trend gave values ranging from 0.99 to 0.01 g/t gold, averaging 0.39 g Au/t.
In 2009, the Ouavousse permit was extended to the north to include two orpailleur areas. In addition, the Poessin area of four mineralized artisanal mining sites, all with shafts in excess of 30 metres deep, is located approximately seven kilometers northwest of the Ouavousse/Markoye area occurrences.
Goldrush is also currently expanding and defining the 249,000 ounce (inferred resource of 5.9 million tones at a grade of 1.31 g/t gold) Ronguen gold deposit in Burkina Faso.
Wednesday morning, Goldrush shares were flat at $0.13.
