Name
Sugar Zone mine.

Location
Northern Ontario, Canada.

Mine Owner/s
Harte Gold Corp.

Brief Description
The Sugar Zone mine is a high-grade underground gold mine.

The Sugar Zone property comprises 309 patented and leased claims covering 79 355 ha.

The mine is producing from the Sugar Zone North and Sugar Zone South areas.

Brief History
The Sugar Zone mine entered commercial production in 2019 and has an expected mine life of 13 years at current production levels.

Primary Metals/Minerals
Gold.

Secondary Metals/Minerals
None stated.

Geology/Mineralisation
The Sugar Zone property is located in the Dayohessarah greenstone belt of late Archean age, which is part of the Abitibi-Wawa subprovince of the Superior province. The belt is about 36 km long and varies in width from 1.5 km to 5.5 km. Principal lithologies in the belt are moderately to highly deformed metamorphosed volcanics, volcanoclastics and sediments that have been enclosed and intruded by tonalitic to granodioritic quartz-porphyry plutons.

Gold mineralisation occurs in quartz veins, stringers and flooded zones predominantly associated with narrow porphyry sills and contact zones, as well as hydrothermally altered mafic metavolcanics, but rarely in weakly altered mafic metavolcanics. 

Reserves
Total proven and probable mineral reserves as at December 31, 2020, were estimated at 3.45-million tonnes grading 7.18 g/t gold.

Resources
Total indicated mineral resources as at December 31, 2020, were estimated at 2.80-million tonnes grading 11.87 g/t gold. Inferred mineral resources were estimated at 1.87-million tonnes grading 9.45 g/t gold.

Mining Method
Underground, using longitudinal retreat stoping.

Major Infrastructure and Equipment
The mine is accessed by a ramp system. The 800  t/d processing plant produces a gold doré bar and bagged gold concentrate through gravity concentration and flotation circuits.

Prospects
The company is exploring an expansion scenario to increase mine and mill throughput by 50%, from 800 t/d to 1 200 t/d.
