In later times, Gold Harbour and Mitchell Inlet became the location of a modern mining operation, also called Tasoo or Tasu, but for iron rather than gold. In 1969, a local logger, Efrem Specogna and his brother-in-law, John Trinco made the initial gold discovery of the Specogna (Babe) Gold deposit west of Port Clements on Graham Island. By ...
It is the largest undeveloped gold deposit in Canada and one of the world's biggest copper-gold porphyry deposits. [5] [6] Though 2P reserves are significant (39 million ounces of gold, 214 million ounces of silver, 9.9 billion pounds of copper and 257 million pounds of molybdenum) they only represent about 65% of the mine's total resource of ...
A variety of gold deposits are formed in accretionary orogens, including orogenic gold deposits. [38] Orogenic gold deposits are typically located in metamorphosed fore-arc and back-arc regions, as well as in the arc [3] and show a close spatial relationship to lamprophyres and associated felsic porphyry dikes and sills.

The highest-grade samples contained 138 grams of gold per ton of ore, surpassing the typical benchmark of eight grams for high-grade deposits. The initial exploration discovered 300 tons of gold ...
Test drills near the site’s “peripheral areas” found more gold, suggesting that the deposit could be even larger. In all, there could be over 1,000 metric tonnes of the precious metal at the ...
After the majority of the gold input was finished, many large scale tectonic and geological events have occurred. Such event ages obtained by the monazite, Rb–Sr, and paleomagnetic studies. During these events the gold was likely remobilized and other ore minerals (e.g. pyrite) formed to create the present day state of Sukhoi Log.
Precious metals as gold, [2] and silver, [3] platinum, nickel and coltan are located in different areas throughout the country. Colombia is the first producer of emeralds and as per February 2017 occupied a ninth position in the production of coal, produced in almost all of the departments of the country.
