The Lordsburg property hosts a copper-gold porphyry system that was discovered by Mason Resources’ predecessor company Entrée Resources Ltd. in 2008.  The property is located in southwest New Mexico approximately 370 kilometres southwest of Albuquerque and covers 2,013 hectares (4,974 acres) adjacent to the historic Lordsburg copper-gold-silver district.  Mason Resources has a 100% interest in the Lordsburg property.

Access to Lordsburg is via Highway 10 from Tucson, Arizona and takes approximately two and a half hours.

A zone of porphyry-style surface alteration and anomalous copper geochemistry exceeds 1.2 kilometres in length and 600 metres in width.  Within this zone, drilling has confirmed sub-surface copper-gold mineralization over a 600 x 600 metre area.  A near surface intersection in hole EG-L-09-012 returned 0.25% copper and 0.15 g/t gold over 94 metres with a copper equivalent (CuEq*) grade of 0.34%, including 60 metres of 0.31% copper and 0.21 g/t gold, with a CuEq grade of 0.44%. Mineralization appears best developed in the contact areas between a feldspar porphyry stock and volcanic rocks. Potassic alteration and sulphide-quartz veining are associated with the strongest areas of mineralization. The district has potential to host “Resolution-style” porphyry deposits and there is district consolidation potential with several majors and other groups holding neighbouring ground.

Twelve holes totalling 6,092 metres were completed in 2008 and 2009 at Lordsburg.  Click here for Lordsburg drill results. Future drilling will be directed towards expanding the existing drill-defined copper and gold zone. 

*CuEq has been calculated using assumed metal prices ($3.00/pound for copper and $1,250/ounce for gold) and no metallurgical factor.
