The net decrease of 123,384 ounces of gold in Proven and Probable Mineral Reserves for end 2023, relative to end 2021, consists of the addition of 13,124 ounces of gold added by Mineral Resource conversion and addition of Mineral rResources to the Shepherd ore body and as well as a total of 110,259 ounces of gold depleted from the December 31, 2021 …
Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3). The industrial importance of antimony is mainly derived from …
MIT's accidental smelting discovery unlocks the potential of antimony. The ancient Egyptians used it in black eye make-up and alchemists marvelled at antimony's semi-metallic properties. Now, a groundbreaking smelting technique could open up new opportunities for antimony, as well as other metals. Nnamdi Anyadike investigates.
The Hillgrove area has seen mining for both gold and antimony since 1857, with continuous antimony production for more than 30 years until 2002 when the price fell to an all-time low. HILLGROVE GOLD-ANTIMONY PROJECT KEY HIGHLIGHTS. The 254km 2 Hillgrove Project contains six key mining areas within 48 granted Mining Licenses

The primary sources of antimony extraction are stibnite (antimony trisulfide) and valentinite (antimony xide). The extraction process typically involves several steps, including mining, concentration, and smelting. Mining involves the extraction of antimony-rich ore from underground or open pit mines.

Mining of antimony ore has been limited to northern Sevier County, although some stibnite is also present in Pike County, associated with cinnabar (HgS). Mined deposits occurred as lenses or pockets of stibnite encased in nearly vertical quartz veins that cut steeply dipping, folded, and faulted beds of the Stanley Shale (Mississippian). ...
While the US has no mined antimony sources, the Stibnite Mining District in Stibnite, ... Historically, ore from SXG's Sunday Creek Project in the Victorian Goldfields was treated onsite or shipped to the Costerfield mine, only 54km to the northwest of the project, for processing during WW1. ...

The most common antimony ore mineral is stibnite (Sb2 S3 ), but more than 100 other minerals also contain antimony. The presence of antimony in surface waters and groundwaters results primarily from rock weathering, soil runoff, and anthropogenic sources. Global emissions of antimony to the atmosphere average 6,100 metric tons per year.
