| Along Rufin Kreek itself, a several hundred metre square surface area is currently being mined from the alluvial gravels up onto the surrounding hillsides where saprolitic intrusive rocks and quartz veinlets are exposed. Its coincidence with artisan gold diggings is comparable to the Sadiola, Syama and Morila mines in Mali which all have a saprolitic and fresh bedrock root. A recent site visit by Brazauro exploration staff revealed several new primary workings hosted in saprolitic granite in the highlands above the main valley, as well as a very interesting sheeted vein swarm about 7 metres wide, in an area exploited by miners since the departure of Rio Tinto. |
