Rio Sonora

The Company has title to a 100% interest in this 42,170 hectare project in two claim blocks located between the copper-molybdenum porphyry deposits at Cananea and Caridad. The claims are underlain by conglomerate valley fill surrounded by bedrock hosting a number of copper occurrences and, in the southern area, strong widespread porphyry style alteration.

The core of each claim block covers magnetic lows similar in magnitude to the magnetic signature over the known porphyry deposits at Cananea and Caridad.

Pembrook entered into an Option and Joint Venture agreement with Vale S.A. on the Rio Sonora property. Under the terms of the agreement Vale can earn up to a 60% interest by incurring expenditures of US$7 million and making cash payments totalling US$400,000 over five years.
