Grenville Begins Road Work at Espanola Property

Grenville's Espanola copper property is located 100 kilometres south of Lima. On May 16, 2007, Grenville reported (see Stockwatch on May 16, 2007) that a total of 45 grab samples of rock were collected from various underground workings. The average of the samples was 0.19 parts per million gold and 2.51 per cent copper. Mineralization on surface is hosted by steeply dipping malachite-stained quartz veins averaging between 0.5 to 3 metres wide. In the underground workings sulphide mineralogy consists of bornite and chalcopyrite. Results are consistent with the former producing Raul/Condestable mines, located 15 kilometres west of Espanola.

In anticipation of further land acquisitions in the Silveria area, exploration at Espanola and for general working capital, Grenville has amended its proposed financing of $ 500,000 from .10 cents to .05 cents. Each Unit will consist of one common share of Grenville and one full share purchase warrant exercisable at a price of $0.15 for a period of two years from the date of issue. All securities issued under the Offering will be subject to a four-month hold period from the date of issue. Grenville may pay a finders' fee consisting of cash/securities of the issuer, or a combination thereof in connection with the offering. This transaction is subject to final documentation and approval of the TSX Venture Exchange.
