Silver Bull Resources appoints vice president of metallurgy

Silver Bull Resources (TSE:SVB) said Friday it has appointed chemical engineer George Rawsthorne as vice president of metallurgy.
With over 40 years of experience in the mining sector, Rawsthorne has held a number of positions that include: mill manager, lead process engineer and has worked as an independent consultant to re-view mining operations for companies and banks.
He has worked in the design and development of metallurgical flow sheets, Silver Bull said in a statement, as well as plant startup and optimizing existing processing plants in an operating environment.
Prior work experience includes (Cominco) Teck Corp., Rabbit Lake Uranium, and Placer Development’s Gibraltar Mine, as well as other junior and mid-tier mining and exploration companies.
“We are extremely pleased to have someone with the experience and history of success of Mr. Rawsthorne join our team,” chief executive Tim Barry said in a statement.
“The goal of finding a suitable metallurgical process to extract both the silver and zinc on a large scale basis is one of our main priorities for 2012.”
Earlier this week, the miner unveiled results for another 10 drill holes targeting the Centenario Zone at its Sierra Mojada project in Mexico.
The company's flagship Sierra Mojada project is located 150 kilometres north of the city of Torreon in Coahuila, Mexico and is highly prospective for silver and zinc.
Among the highlights, two drill holes encountered 100-plus metre intercepts of silver oxide mineralization intersecting high grade zones of 417.64 grams per tonne (g/t) silver over 10 metres, 283.89 g/t silver over 13.05 metres and 176.77 g/t silver over 21.5 metres.
Silver Bull’s share price traded steady at 57 cents apiece on the Toronto Stock Exchange on Friday afternoon.
