SnapshotThe Mallay Property is comprised of the concessions encompassing the past-producing Mallay Mine (was placed on care-and-maintenance in 2018) and the Tres Cerros Exploration Property.

Fully permitted to restart production, existing infrastructure includes working mill, operational water treatment plant, adit and ramp access to the mine, significant underground development and active workforce. Current mineralized inventory is believed to be sufficient for the basis of a three-year mine plan, the expected six-month restart period includes mine rehabilitation and mill controls upgrade.

Following closing of the Acquisition, Excellon intends to update the resource calculation to become NI 43-101 compliant, taking into account not only updated metals prices, but additional extension drilling Excellon anticipates to undertake, demonstrating the continued extension of current mineralized zones.

Deposit type

  • Epithermal
  • Replacement
  • Vein / narrow vein
  • Mesothermal

Summary:

Mallay is considered an epithermal deposit of silver, lead, zinc and limited gold values.

Mallay is a fracture-filling and replacement-type mesothermal deposit, with Ag-Pb-Zn mineralization. Many of the mineralized structures are located in quartz arenites from Farrat Formation, while another part is emplaced in Jumasha limestones. The main structure is Isguiz, emplaced in the north flank of the anticlinal of the same name. From here, a series of tensional veins run E-W. In Jumasha limestone, further north, is the Pierina veins system, with similar mineralization, but with the occurrence of gold.

The exploitation of ore is primarily focused on the following main ore structures: Isguiz body-vein (silver, lead, zinc), Pierina vein (gold), MarĂ­a vein (silver) and Fortuna (skarn type lead, zinc and silver).
