Minera del Norte S.A. de C.V. (MINOSA), a leading coal company in Mexico and a subsidiary of Grupo Acerero del Norte (GAN), was selected as the recipient for a pre-feasibility study for CMM drainage at their Conchas Mine Complex in the southern Sabinas Basin of Mexico. The objectives of this pre-feasibility study are to perform an initial assessment of the technical and economic viability of methane drainage utilizing vertical pre-drainage boreholes drilled from the surface, and to identify end-use options.
