Sierra Metals (TSXV:SMT) expanded drilling depth at its Yauricocha mine in Peru and has extended mineralization at an additional 150 meters at the Rosaura and Antacaca Sur orebodies. “The high grade intercepts over wide widths … indicate that the mineralizing processes in this area were strong even in the deepest levels of the mine and we expect that these orebodies will continue to significant depths,” CEO Daniel Tellechea said in a statement.

Redhawk Resources (TSX:RDK) acquired over 1.4 square miles of additional properties adjacent to its Copper Creek project in Arizona, bringing the total land package to around 35 square miles. The added land is patented and subject to exploration and may potentially contain mineral resources.

Curis Resources (TSX:CUV) said a metallurgical test in advance of a prefeasibility study at its Florence copper project in Arizona suggests that “overall copper recovery of approximately 70 percent will be achieved from a typical mineralized block.” General manager Dan Johnson said in a statement that “[i]mproved copper recoveries, combined with a revised mineral extraction plan and updated capital and operating cost estimates, are expected to further confirm Florence Copper as having the potential to be one of the lowest cost near term copper producers in the world.”

Tirex Resouces (TSXV:TXX) received all mining licenses and environmental permits for its Mirdita project in Albania, meaning that mining operations can now start.
