Celeste is currently focused on the acquisition of an interest in Cornish Minerals Limited, which controls mining rights in the historic Cornish mining region in Cornwall, England, including the South Crofty Mine.
Celeste also assesses other tin, copper and copper-gold properties for exploration and development.
Shoesmith brings Celeste 40 years of commercial experience, having previously been CEO of The Shaw Group, a highly diversified group of companies overseeing operations in specialist engineering, manufacturing and property management.
"I am excited to be working with the Celeste management team to bring its historical Mine project in Cornwall, England back into production," said Shoesmith.
"South Crofty is a poly-metallicproject with the potential scale to create a significant value opportunity for Celeste's shareholders."
Since 2001, Shoesmith has been CEO of Baseresult Holdings, and subsequently Western United Mines, the operating arm of Celeste's partially owned subsidiary Cornish Minerals Limited.
In this capacity, he had oversight of South Crofty and managed all activities in relation to the commercial, governmental permit, planning and mineral right aspects to the project.
"We are pleased to have Alan join Celeste as he is an experienced senior executive and he has guided the company's key asset, the South Crofty Project, since the mine was acquired in 2001," said chairman of Celeste, Farhad Abasov.
"I know Alan is committed to bringing this important project back into production and helping the Celeste team realize the value that our exciting projects represent for our shareholders. I look forward to working with him."
Celeste also announced Tuesday that Norman Brewster will be resigning as the company's president and CEO, but that he will remain actively involved with the company as a member of the board of directors.
The company said last week that it has extended an earn-in agreement to acquire an initial 25 percent equity interest in Cornish Minerals Limited. The company extended the expiry date of the earn-in agreement, signed in May 2011, to June 30,2012.
The Calgary-based company also recently reported that it has gained additional property assets to facilitate the construction of the future surface infrastructure at South Crofty.
Earlier this year, Cornwall Council - the project's local mineral planning authority - granted new conditional planning consents for developing new surface mine infrastructure and for the extension of the mine's underground working area to 1,460 hectares from 510 hectares.
