This Cu-As-Ag vein discovered in the 16th century is the second from the back of the Rauenthal valley and one of the well known worldwide mines for its Ca-Mg arsenate minerals (7 type locality species), native arsenic and silver sulfoantimonide-sulfoarsenide minerals (1 type locality species).
Zero level was joined by the Tiefstollen adit (1500 m from entry) for water drainage only by underground access at -100 m level (Gabe Gottes is the zero level).

Gabe Gottes is one of the mines which worked the Sankt Jakob vein, Giftgrube and Buchhalterschacht mine where too. The Sankt Jacob vein splits in two and the Gabe Gottes exploited the south vein. During centuries there where some name changes. From the 16th to the 17th century, the name for Gabe Gottes was Heilige Kreuz. Sankt-Ulrich and Sankt-Jakob high were the name of actual Giftgrube which owes its name to the abundance of secondary arsenic minerals formed on large blocks of massive arsenic, used as underground support material by the old miners.
From discovery to end of exploitation, different periods where sometimes related and reported. Despite some periods of wealth followed by bankruptcy with the depletion of deep veins and the Thirty Years War (1633-1663). Two reports, written in 1586 and 1633, describe several projects that where underway in a hard rock that disrupts the profitability of operations in Saint-Jacques (P & T n "6).
In the Rauenthal valley, mining restarted in 1711 for cobalt but it was not until 1720 that a license application on the Sankt Jakob vein was granted. Several reports dating back to the 18th century will recount the prestigious discoveries, job status and staffing. Its peak was reached from 1735 to 1736 with an annual production of 4400 silver marks (almost 1100 kg).

Gabe Gottes was the most recent Neuenberg mine, worked only for arsenic metal from 1932 until 1940.

As this locality lies in the Sainte Marie-aux-Mines district, the place is protected by a archaeological mining district status and all collecting is prohibited.
