Apollo Minerals receives high-grade gold and tungsten results from historical Couflens data

The company’s focus is on reactivating the Salau tungsten mine in France, one of the world’s highest grade tungsten mines in the 1980s.

Apollo Minerals Limited (ASX:AON) has identified high-grade gold and tungsten in newly obtained data from the historical Salau mine within its Couflens project in France.

The historical gold assay results confirm the presence of high-grade gold values within the mine and at depths of around 600 metres below surface.

This highlights the significant scale of potential of the exploration opportunity at the project.

High-grade results

The archive includes previously unavailable reports on gold assays results from 1986 from historical channel sampling and drilling inside the Salau mine including:

  • Up to 1.9 metres at 16 g/t gold from channel sampling programs; and

  • 8.5 metres at 3.4 g/t gold, including 1.9 metres at 8.4 g/t gold from diamond drilling results within the mined area.

The archive also has information on more than 1,000 drill holes and channel samples and contains more than 100 boxes of geological maps, sections drill logs and assays for tungsten from drilling.

“Excited by the high-grade gold grades”

Apollo Minerals executive director Hugo Schumann said: “We are excited by the high-grade gold grades that were reported historically, including 8.5 metres at 3.4 g/t gold from drilling and 1.9 metres at 16 g/t gold from channel samples.

“These grades, reported from inside the mine, are comparable to the high gold grades obtained at surface and have been identified along many kilometres of strike length.

Enhances geological understanding

“This valuable archive obtained from the former mine operators greatly enhances our geological understanding of the historical Salau mine and regional potential of the Couflens project.

“The fact that we now have access to the more than 1,000 drill holes and channel samples represents a huge saving in cost and time and significantly de-risks our exploration programs.

“Our focus it to rapidly commence a program of in-mine channel sampling and drilling immediately after the soon-to-be-completed health and safety risk assessments.”

A general global average for a tungsten mine might run at around 0.3% tungsten trioxide (WO3) whereas grades at Couflens are at an average of 1.5% and were as high as 2.5% WO3 when the mine closed about 40 years ago.


Following the acquisition of the Couflens project in March 2017, the company obtained the historical database and has now been granted a second set of archives.

The archive will be reviewed and incorporated into the company’s database, representing an additional saving in cost and time by de-risking the upcoming exploration and study programs.

A program of in mine channel sampling will occur in order to confirm the veracity of the historical data and to test for extensions to known mineralisation.
