The Silveria project’s 3959 Ha covers a group of four past-producing silver-copper-lead-zinc mines 65 miles east of Lima, Peru. The mines were shut down due to financial difficulties caused by political turmoil in the early 1990s. Based on published information, mine plans, production records and reserve calculations obtained from operators of the two mines, the minimum historical production from two of the four mines indicates 39 million ounces of silver, 88 million pounds of copper and 96.8 million pounds of zinc were produced.

("Chinalco"), a Company representing Chinese interests.
