This property is owned by QMX Gold which was formerly known as Alexis Resources Ltd. On January 26, 2012, Alexis formally changes its name to QMX Gold. The Lac Herbin properties covers a total aggregate surface area of 9,706.87 hectares. The Aurbel-Lac Herbin group of properties comprises 431 claims, 4 mining leases and one surface lease. The properties include two past mining operations, the Dumont and Ferderber mines where approximately 610,000 ounces of gold were produced; a milling complex, the Aurbel Mill; and the Lac Herbin gold mine.

Gold exploration on the Aurbel property dates back to 1920 and culminated with the mining of two deposits, the Dumont and Ferderber mines between 1980 and 1994. The first intersection linked to the Lac Herbin deposit was hit by surface diamond drilling in January 1995 by Aur Resources. The Lac Herbin zone was intersected by 23 holes during this program, and the WE zone was also identified.
In May 2003, Alexis Minerals Corporation entered into an option agreement with Aur, whereby Alexis could earn a 50% interest in the Aurbel property by making cash payments and spending $5 million in exploration expenditures on the property by March of 2006. Alexis also had the right to purchase the remaining 50% Aur interest and the Belmoral mill subsequent to March 2006.

In February 2006, Alexis vested into a 50% interest on the Aurbel property, pursuant to its May 2003 agreement with Aur. Alexis exercised a second option to purchase the remaining 50% interest in the property and the Belmoral gold mill, located centrally on the property, for $3 million in cash. The acquisition closed during the third quarter of 2006. A four-phase program of underground exploration was authorized in July 2005 on the Lac Herbin project. Permitting and surface installations were completed for ramp development start-up on September 1st, 2005. Ramp and level development as well as proposed delineation drilling of Phase I and Phase II were completed; Phase III was entered in the third quarter of 2006.

Phase III included over 500 meters of lateral development focused on mining of a bulk sample of mineralized vein material for custom milling during the fourth quarter of 2006. Phase IV was entered in 2007 and included ramp, lateral, level and sub-level development (2,556 m), ore development (471.4 m) exploration and delineation diamond drilling (32,024 m), and long hole and room-and-pillar stoping (46,410 tm) in the course of a second bulk sample milled in November and December 2007. These programs were successful at proving the economic viability of the Lac Herbin deposit. Exploration and delineation diamond drilling as well as main ramp, lateral and ore development continued throughout 2008. Alexis directly hired maintenance, development and mining crews. Long hole stoping was performed in the S3, LH and HW zones. Mechanized cut-and-fill was also performed in the S3 Zone.

The mine was inaugurated in October 2008 and officially entered production. A total of 80,284 t were produced from underground in 2008 for 17,868 oz Au. The mine operated full-time in 2009 and produced 170,658 t for 32,900 oz Au from development and stoping in the S1, S2, S3 and HW zones. The mine operated full-time in 2009 and produced 170,658 t for 32,999 oz Au from development and stoping in the S1, S2, S3 and HW zones. Total development dropped to 2,155 m. In 2010, the mine produced 133,059 tonnes for 21,557 oz Au from several headings including the S1, S3, HW, HW2, LH, and WE. Grades and tonnages decreased due to lower grades and smaller stopes in more peripheral areas of the S1 and S3 along with other secondary structures with less than expected continuity
of grade. Total linear development stands at 2,476 m for 2010.
