The Montauban region has a high environmental legacy of contamination by historical tailings and it is the objective of the Company to correct the situation by removing as much tailings as possible from these lands and stabilize them into a new tailings site. The Company is fully permitted for its mill and most of its tailings’ tonnage.
The Montauban Gold Project comprises five principal tailings sites: Anacon Lead 1, Anacon Lead 2, Tétreault 1 and Tétreault 2 (the “Montauban tailings”), and the NotreDame-de-Montauban tailings, all of which were generated during the processing of ore from the historic underground Montauban Mine, which hosted a gold-rich VMS deposit.
The current permitting status allows for the reprocessing of tailings from the Anacon Lead 1 tailings site. A CA for the reprocessing of tailings from the other tailings sites is required. |

Summary:
Mineralization
There is no primary precious-metal mineralization on the Property; however, there are five (5) tailings sites on the Property that were generated during the processing of ore from the historic underground Montauban Mine, which hosted a gold-rich VMS deposit. Secova proposes to mine the Anacon Lead 1 tailings site, which has average gold (Au) and silver (Ag) grades of 0.28 g/t (Au) and 27.10 g/t (Ag), and is delineated over an area of 695 m x 195 m, with a depth of 45 m.
Summary:
The operational design is to bring the tailings pile material to the pump box near the processing plant.
The objective is to feed 270,000 t of tailings to the processing plant for the first three (3) years and 113,000 t during the fourth year of operation, for a four-year total of 923,000 metric tonnes. The contractor at the mining operation will work on a 9-month per annum basis avoiding operations during the coldest months.
The material will be picked up by a shovel (Cat 336 type) or a loader (Cat 966 type).
The hauling work can be done by a single articulated truck (Cat 730 type) with a capacity of 14 cubic metres. A second truck will be available on-site as backup.
The truck will unload near the pump box (plumper) and a loader will pick up the material to feed the plumper via a hopper, the objective being to have the tailings in slurry for pumping and mill feed. At short distance, the excavator will discharge directly on the hopper at the plumper. The work will be contracted out on a 24-7 basis.
As the Anacon Lead 1 pile is close to the processing plant, at the beginning of production a wheel loader will be used to load the truck and the same loader could load the plumper by driving down to the plant. As production advances, the wheel loader will not be able to do both tasks and a shovel should be brought to the pile to do carry out one of the tasks.
There will be a buffer of 500 t (12 hours of feed) stock ........
