Canadian midtier gold producer Gran Colombia Gold has signed a definitive agreement to complete a business combination with junior miner Gold X Mining and has submitted a proposal to Guyana Goldfields to acquire all its issued and outstanding common shares. Through the combination of the three companies, Gran Columbia is seeking to create a new Latin American intermediate gold producer. The company believes its offer represents a superior proposal to the arrangement that Guyana Goldfields and Silvercorp Metals entered into last month.
