La Mancha Resources Inc. shares gained 52 per cent after a firm run by an Egyptian billionaire offered to buy the gold miner for $499.5-million.
The Montreal-based miner said Friday that the investment company Weather Investments II, owned by Naguib Sawiris, founder of Orascom Telecom Holding, has offered $3.50 per share in cash for La Mancha.
The offer was a 55.6 per cent premium to the company's closing price Thursday on the Toronto Stock Exchange.
After the offer was announced, La Mancha's shares jumped $1.18 to $3.43, still slightly lower than the offer price.
"While offering a significant premium to our shareholders, this transaction will enable the La Mancha team to pursue the development of its projects with its partners in Sudan, Côte d'Ivoire and Australia with the support of a strong financial partner," said Dominique Delorme, president and CEO of La Mancha.
"We are delighted by the show of confidence expressed by Weather II through this transaction and are looking forward to put our operating and development expertise at their service".
La Mancha announced in March that it had formed a special committee of independent directors to conduct an auction seeking acquisition proposals.
La Mancha's board has unanimously agreed to recommend the offer to shareholders.
The company has two gold mines in Africa and two more in Australia.
Egypt's Sawiris family also has interests in the telecom, construction and fertilizers, cement, real estate and hotel development industries. Orascom holds a substantial stake in Canadian wireless firm Wind Mobile.
Mr. Sawiris, chairman and CEO of Weather II, said La Mancha is an extremely attractive company with a geographically diverse portfolio with exposure to growth and development-stage projects.
"We look forward to working with the strong management team to realize the full potential of the company going forward."
La Mancha's largest shareholder, Compagnie Française de Mines et Metaux, which requested the auction the process, said it plans to tender all of its shares to Weather, representing 62.8 per cent of outstanding shares.
Under a lock-up agreement the shareholder cannot tender its shares to a competitor.
La Mancha cannot solicit other offers other offers under terms of the deal and would face a break fee of $15-million if the acquisition isn't completed.
