Arrow Mineral’s just identified a giant, previously unknown gold system at its Vranso project in Burkina Faso.

The extraordinary 50sqkm discovery was made using Arrow’s cutting-edge stream sediment geochemical sampling, highlighting the value of using modern gold exploration techniques, being applied for the first time in this highly prospective greenfields area.

Arrow Minerals’ (ASX:AMD) managing director and CEO, Howard Golden told Stockhead the collation of 220 stream sediment samples over a 580sqkm area highlighted gold anomalous drainages consistently sheading from a major regional mineralised structure. 

Golden years

A geophysicist with over 30 years’ experience exploring across six continents, Golden has led teams across globally significant finds from Syama, Oyu Tolgoi, Agbaou to West Musgrave.

And while he’s been with Nordgold, Rio and BHP, it’s his operating experience throughout West Africa which makes today’s announcement particularly exciting.

“This structure is interpreted to be an extension of the same mineralized structure that hosts the Sanguie, Guido and Semapoun prospects to the project’s south,”he said.

A second phase of stream sediment geochemical sampling is now underway within the anomalous area and surrounds to assist with vectoring in on the main mineralised gold system.

Also exciting Golden’s team: the stream sediment assays are the first results from a large multifaceted exploration program in progress at Vranso.

Other work such as soil sampling, reverse circulation drilling and auger drilled are also underway with results to be validated, analysed and reported very soon.

The company also plans to carry out an airborne geophysical survey later this quarter.

Vranso project

Vranso – located 100km west of Ouagadougou – consists of 10 semi-contiguous exploration permits extending for over 80km along the main northeast-southwest trending Boromo Shear Zone that is host to numerous multi-million ounce gold deposits such as Bissa, Bouly, Poura and Batie West.

It also covers 1,300sqkm of the richly gold endowed Paleoproterozoic Birimian Greenstone Belt, most of which remains to be evaluated using modern techniques.

The project also hosts a number of drill-ready gold prospects within a 20km radius of the Perkoa of which the Dassa, Guido Semapoun and Bantole are the most advanced with previous drilling yielding gold intersections such as 33m grading 1.9 grams per tonne (g/t) gold and 4m at +25g/t gold.
