Brazil's Camargo preparing bid for Cimpor -

LISBON, Dec 21 (Reuters) - At least one more Brazilian company, Camargo Correa, may bid for Cimpor, Portugal's biggest cement maker, following last Friday's takeover offer from CSN (CSNA3.SA), Portuguese media said on Monday.

The "i" daily cited a source familiar with the situation as saying the Camargo Correa construction conglomerate will seek not more than a third of Cimpor in a "much friendlier approach than that by CSN".

"There are various possibilities, a cash offer or a deal that can involve merging businesses ... The Camargo proposal should be unveiled on Tuesday or Wednesday and it will be a different model from CSN," i quoted the source as saying.

Jornal de Negocios and Diario Economico business newspapers also said Camargo was preparing a bid, which might target a large minority stake rather than all of the company as is being sought by the steelmaker CSN [ID:nLDE5BH0IK].

Cimpor shares, which surged 16 percent on Friday, added 1.6 percent in early trading on Monday to fetch 6.44 euros -- its highest level in nearly two and a half years.

Contacted by Reuters, a Camargo Correa representative in Lisbon said "there is nothing to announce yet".

Other potential bidders mentioned by local media are Brazil's Votorantim conglomerate, Switzerland's Holcim (HOLN.VX) and Mexico's Cemex (CMXCPO.MX).

France's Lafarge (LAFP.PA) owns a 17 percent stake in Cimpor, but analysts see a bid by the world's top cement producer unlikely at the moment as it has been divesting of late after being hard-hit by the global recession. Lafarge has declined to comment on the matter.
