International Enexco Completes Drill Program at Contact Copper Project and Reports Remaining Assays

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 10, 2012) - International Enexco Ltd. (TSX VENTURE:IEC)(OTCQX:IEXCF)(FRANKFURT:IE6) (the "Company" or "Enexco") is pleased to announce that the remaining assay results have been received from the 2011-2012 drill program on its 100%-owned Contact Copper Project ("Contact"). All assay results from the program will now be incorporated into an updated mineral resource estimate that is expected this Fall. In addition, a full review of the 2011-2012 exploration program is underway in order to help identify additional exploration and pre-development actions required for the on-going development of Contact. Management is also focusing on additional unexplored targets that are Contact extensions or new areas within the district that have shown opportunity for copper mineralization.

Highlights from the remaining assay results released today include:

  • All assays completed, 42,418 feet (12,932 metres)
  • 0.40% Copper over 90 feet (27 metres) in EN-172
  • 0.57% Copper over 20 feet (6 metres) in EN-178
  • 0.44% Copper over 27 feet (8 metres) in EN-180
  • Update of Mineral Resource in Progress

"The successful completion of our recent drill program marks another step in the development of Contact and allows us to update our resource estimates in preparation for a feasibility study. Although our focus is on the current resource area, we are excited about our land position, which is allowing us to identify other promising areas for exploration and advance them towards drilling," commented President & CEO Arnold Armstrong.

Drilling on the east end of the project this year added over 3,000 feet (914 m) of strike length to the identified copper oxide mineralization, which now extends over 7,250 feet (2,210 m) in length. The results today include ten core holes; eight were drilled on the east extension, in the down-dip direction of copper bearing zones encountered earlier this year. The remaining two core holes were drilled on the west end as in-fill holes and demonstrate continuity in previous drilling. Of the ten holes drilled, nine contained multiple intervals of copper oxides grading above 0.10% copper. EN-172 intersected the thickest continuous interval; with 0.40% Cu over 90 feet (27 m) down-dip from previously reported RC holes ENR-8 and ENR-14.

The current mineral resources for the Contact Copper Project are as estimated in the 2010 NI 43-101Technical Report Pre-feasibility Study Update for the Contact Copper Project, Elko County, Nevada, as posted on Sedar.
