Summary:
The Lapa property is located near the southern boundary of the Archean-age (2.7 billion years old) Abitibi Subprovince and the Pontiac Subprovince within the Superior Province of the Canadian Shield. The most important regional structure is the Cadillac-Larder Lake (CLL) fault zone marking the contact between the Abitibi and Pontiac Subprovinces. The fault zone passes through the property from west to east, and is marked by schists and mafic to ultramafic volcanic flows that comprise the Piché group (up to approximately 300 metres thick in the mine area). On the Lapa property, the fault zone displays a "Z" shaped fold to which all of the lithologic groups in the region conform. Feldspathic dykes cut the Piché group, especially near the fold. North of the Piché group lies the Cadillac sedimentary group, which consists of 500 metres or more of well-banded wacke, conglomerate and siltstone with intercalations of iron formation. The Pontiac group sedimentary rocks (up to approximately 300 metres thick) that occur to the south of the Piché group are similar to the Cadillac group but do not contain conglomerate nor iron formation.
All of the known gold mineralization along the CLL fault zone is epigenetic (late) vein type, controlled by the structure. The mineralization is associated with the fault zone and occurs within or immediately adjacent to the Piché group rocks.
The Lapa deposit is comprised of the Contact Zone and five satellite zones. The Contact Z ........

Longitudinal retreat
Cemented backfill
Summary:
Lapa hosts an underground mining operation accessed by a 1,369-metre-deep shaft. Two mining methods are used – longitudinal retreat with cemented backfill, and locally transverse open stoping with cemented backfill. The dilution rate for mining the reserves averages 71%. The production rate has risen to 1,700 tonnes per day.
