Rocmec obtains patent for its thermal fragmentation mining method for Brazil

Vaudreuil-Dorion (Quebec), April 8, 2013 – Rocmec Mining Inc. (the “Corporation” or “Rocmec”) (TSX-V Symbol: RMI), is pleased to announce that it has received confirmation of the issuance of a patent pertaining to Rocmec`s thermal fragmentation mining method for Brazil. The patent number for Brazil is P10316614-7 and is dated December 11th, 2012. The patent portfolio of the Company now includes the following countries:  Australia, Brazil, Canada, China, Mexico, Morocco, Russia, South Africa, Tanzania and the United States. This is an important milestone for the company given Brazil’s significance in the global mining industry.

“The issuance of our patent in Brazil is a strategic addition to our patent portfolio positioning Rocmec as a totally unique Hybrid mining and technology Company. The patents acquired over the years are key to the growth of our Company along with its mining operations, such as our Rocmec 1 gold property. The recent lack of discovery of large world class deposits and the need to optimise existing mine production represent a promising market for Rocmec’s thermal fragmentation mining process. Independent data gathered for the use of our exclusive patented thermal fragmentation mining method will help us to prove that our technology can become a market changer, gradually gaining recognition as a definite solution to current problems faced by the mining industry such as; increasing extraction costs and uncontrolled dilution”, said André Savard, President & CEO of Rocmec.

The mining of high-grade, narrow vein deposits is an important field of activity in the precious metal mining sector. The main factor undermining the profitability and effectiveness of mining such ore zones is the substantial dilution that occurs when blasting with explosives during extraction. The Thermal Fragmentation mining method can be used as a stand-alone method or it can be used as a complement to any conventional mining methods used in wider vein precious metal deposits.

In order to minimize dilution, the Thermal Fragmentation Mining Method enables the operator to extract a narrow mineralized corridor, 30 cm to 1 metre wide (according to the width of the vein), between two sub-level drifts. By inserting a strong burner powered by diesel fuel and compressed air into a pilot hole previously drilled directly into the vein, a thermal reaction is created, spalling the rock and enlarging the hole up to 1 metre in diameter leaving the waste walls intact. This patented method produces highly concentrated ore, resulting in 400% - 500% less dilution when compared to conventional mining methods.

The mining method also reduces the negative environmental effects of mining operations since much smaller quantities of rock are displaced, stockpiled and treated using chemical agents. The fully mechanized equipment operated by a 2-person team (1 thermal unit operator, 1 drill unit operator) maximizes the effectiveness of skilled personnel, and increases productivity and safety.
The Corporation also announces that the Board of Directors granted a total of 100,000 options to purchase Common Shares to an arms length service provider mandated to provide expertise in technology development and strategic market positioning. These options have an exercise price of $ 0.10 per Common Share and an exercise period of 5 years.

Rocmec is active in the exploration and the development of gold resources in Quebec and Peru. The Corporation owns a gold property with resources recognised in accordance with NI43-101, a modular treatment plant and an exclusive license for a thermal fragmentation mining method for exploiting narrow-vein ore deposits.

The company’s growth strategy is:

• To develop  its wholly-owned gold deposits and produce  revenue;
• To increase the value of its mining assets by prioritizing exploration targets; and
• To commercialize its thermal fragmentation technology.
