Company Description
In 1995, valuable calcite deposits were discovered in Northern Utah. Shamrock Mining Associates gained exclusive mining rights to this unique and beautiful semi-precious Amber Onyx, also known as Honeycomb calcite or Honey Onyx.
Summer 1997 marked the beginning of substantial mining and exploration operations. Early exploration conducted on the seven mining claims owned by Shamrock indicated proven reserves of 363,280 tons and probable reserves of 1,636,400 tons. Over the following seven years, Shamrock filed 15 additional claims. No drilling has been conducted as yet on these claims, but it is likely that surface outcrops of calcite present in the central area of the claim-block extend onto additional claims in the shallow subsurface.
