TORONTO, ONTARIO--(Marketwire - May 17, 2010) - Colossus Minerals Inc. (TSX:CSI) ("Colossus" or "the Company") is pleased to announce that the shareholders of its joint venture partner, COOMIGASP (Cooperativa de Mineração dos Garimpeiros de Serra Pelada), have approved the previously announced option agreement with Vale S.A. ("Vale Option Agreement") to acquire a 100% interest to mine precious metals in a 700 hectare land package ("Area B") contiguous to the existing 100 hectare Serra Pelada Project ("Area A") currently being developed by Colossus and COOMIGASP. In addition, the agreements between Colossus, through its Brazilian subsidiary ("Colossus Brazil"), and COOMIGASP ("CC Agreement") covering the transfer of the Vale Option Agreement into Serra Pelada Companhia de Desenvolvimento Mineral ("SPC"), the Colossus/COOMIGASP joint venture company, and the transfer to SPC of an approximate 74‐hectare tenement currently owned 100% by COOMIGASP ("Area C") also received shareholder approval (see press release dated March 30, 2010).

As previously announced, the CC Agreement obligates Colossus to pay COOMIGASP $12 million Reais (approximately US$6.7 million) plus a fee of $300 Reais for each kilogram of gold, platinum, palladium or other platinum group elements sold from Area B (equivalent to US$5.23 per ounce) to cover all obligations of the Vale Option Agreement, and to pay COOMIGASP $1450 Reais for each kilo of gold, platinum, palladium or other platinum group elements produced and sold from Area C (equivalent to US$25.26 per ounce). The currency conversion rate used in this news release is $1.00 Real equals US $0.56.

Details of the Vale Option Agreement are as follows:

1. A three year option agreement was signed to acquire a 100% interest in Area B to mine precious metals.
2. COOMIGASP commits to a minimum exploration expenditure of US$5 million over three years on Area B.
3. An estimate of the mineral reserves (proven + probable) ("Mineral Reserves") under internationally accepted guidelines must be completed by the end of the 3 years in order to exercise the option.
4. Colossus, through SPC, will pay US$35 per ounce of gold, platinum or palladium (the "fee") based on the Mineral Reserves and 20% of the fee will be paid 30 days after exercising the option with the remaining 80% to be paid 90 days after the publication of the transfer of the mineral rights of Area B from Vale to COOMIGASP and subsequently to SPC.

Details of the CC Agreement are as follows:

1. Colossus will pay COOMIGASP $12 million Reais (approximately US$6.7 million), of which $8 million Reais (approximately US$4.5 million) is for assignment of the Vale Option Agreement to SPC and $4 million Reais (approximately US$2.2 million) is for the acquisition of Area C.
2. Colossus assumes all financial responsibilities of COOMIGASP under the Vale Option Agreement.
3. Colossus will pay COOMIGASP $300 Reais for each kilogram of gold, platinum, palladium or other platinum group elements sold from Area B (equivalent to US$5.23 per ounce).
4. Colossus will pay COOMIGASP $1450 Reais for each kilogram of gold, platinum, palladium or other platinum group elements produced and sold from Area C (equivalent to US$25.26 per ounce).

In all cases, funding required by SPC to fulfill the terms of the CC Agreement and the Vale Option Agreement commitments will be supplied by Colossus Brazil as an equity contribution to SPC such that the shareholding of SPC remains at 75% for Colossus and 25% for COOMIGASP.

"Colossus will announce in the near future plans for an exploration program on the newly acquired ground. Also I would like to thank our joint venture partner for moving forward expeditiously in obtaining shareholder approval for all of the agreements", stated Ari Sussman, CEO of Colossus. "We are excited to get to work exploring the extension of the known deposit and searching for additional targets on the new ground."
