Hummingbird Resources, the Birmingham firm drilling for gold in Africa, has taken a step closer to producing the precious metal by forming a technical advisory committee.

Jewellery Quarter firm Hummingbird, which has identified more than £3.5 billion worth of gold at its Dugbe prospect in Liberia, has recruited two experts to help it realise the find.

The advisory committee will initially consist of two independent industry experts, Mark Calderwood and Michael Skead, together with David Pelham from the company.

Mr Calderwood has extensive experience working with both exploration and production companies in West Africa, while Mr Skead is a geologist with significant international experience of mineral exploration, with particular expertise working in Africa.

The Birmingham Post reported earlier this year that Hummingbird had total funding of £16.4 million in place for 2013, following deals last year with Anglo Pacific and IFC, part of the World Bank.

Dan Betts, chief executive of Hummingbird, said the move was part of a “transition from explorer to developer and producer”.

He added: “The appointment of these highly skilled industry professionals will be a great benefit to Hummingbird and serves as a strong endorsement of the company’s vision and strategy.”

Hummingbird Resources span out of Mr Betts’ family firm, Jewellery Quarter-based Betts Metals, which has been trading gold in the city for 250 years.
