Unit price per1 low in stock
This is a fantastic crystallized chalcopyrite matrix core sample. The specimen is rounded with brassy chalcopyrite, pyrite and grossular crystals. The Grasberg mine has the single largest known gold reserve and the second largest copper reserves in the world. It is located 96km north of Timika, at Tembagapura in Irian Jaya – the most easterly of Indonesia’s provinces – on the western half of the island of New Guinea. The mine stands at the collision of the Indo-Australian and the Pacific tectonic plates.
The Grasberg minerals district includes open-pit and underground mines. The mining of the final phase of the Grasberg open pit was completed in 2019 and the mine transitioned from open-pit mining to large-scale underground mining.
A mine core sample is a cylindrical piece of rock, often several inches in diameter, extracted from the earth by a drilling rig to explore for pyrite deposits. These samples are used to physically examine the rock's geology, identify different mineral types like pyrite, and measure their abundance and distribution. Core samples are critical for determining the economic viability of a mine and are analyzed using methods such as visual inspection, microscopic examination, and chemical techniques.
This top specimen is in perfect condition. Would be a beautiful addition to any new or existing collection.
