The 903 Zone is situated within the Destor–Porcupine Fault and is open to the east, west and at depth. The deposit was first explored by Wright Hargreaves Mines Ltd. in the 1940’s as linear syenite dykes hosted within the main structural zone of the Destor-Porcupine Fault.
The 903 Zone presents a significant opportunity for resource growth on the Garrison Gold Project.
- In September of 2013 the Company acquired a 100% ownership of the claims covering the western extension of the 903 Zone from Lac Properties a subsidiary of Barrick Gold Corp (see Press Release).
- In late 2013 the company completed a 1914m diamond drill program to test the 903 zone along 550m of strike length. Highlights of the 2013 drill program include:
- Historically over 50 drill holes have tested the zone along 720m of strike length and to depths exceeding 300m vertically
- -3.21 g/t Au over 3.6m (311.5-315.1m) 903-13-04
-4.67 g/t Au over 7.1m (34.9 to 42.0m) 903-13-05
-3.21g/t Au over 8.0m (312.0 to 320.0m) 903-13-05
-2.60 g/t Au over 17.0m (58.0 to 75.0m) 903-13-06
The 903 Zone occurs within linear syenite dykes hosted within sheared ultramafics of the Destor-Porcupine Fault zone. The syenite dykes have widths ranging from several meters to tens of meters and can be traced along strike for hundreds of meters. Typical mineralized widths range from 10 to 20m.
The syenite bodies show considerable chloritic fracturing and the development of narrow (1-5cm) quartz stringers and veins. Sulphide content generally ranges from trace to 5% and higher sulphide content is typically coincident with higher gold grades. Rarely visible gold is observed in the quartz veins and stringers.
Peripheral mineralization (Hastings North and South Zones) occurs within Temiskaming type metasedimentary hosts where very strong silicification, brecciation and quartz vein development occur. The peripheral zone’s mineralization is similar to the bulk tonnage Garrcon deposit located 1 km to the east.
Mineralization extends over 720 meters of strike length and occurs as multiple parallel zones across a width of 150m. The zone has been traced to depths of 300m with diamond drilling and remains open at depth.
Gold mineralization in the main 903 zone is entirely hosted within the syenite dykes and the surrounding ultramafic assemblages are typically barren of mineralization.
The 903 Zone was originally discovered by Wright-Hargreaves Mines Ltd. who conducted exploration drilling along the Destor-Porcupine fault in 1945. Around the same time the zone was intersected by drilling on the neighbouring property under option by Dome Mines Ltd. Between 1945 and 1947 Dome Mines and Wright-Hargreaves Mines drilled 44 holes to explore the deposit.
In 1983 Lac Minerals acquired the property held by Wright-Hargreaves Mines and completed 5 drill holes along the western extent of the 903 deposit with encouraging results.
In 1987 Lac Minerals completed a further 11 drill holes along the 903 zone and discovered the Hastings South Zone by testing that zone with 4 drill holes.
In 1991 Lac Minerals and joint venture partner Jonpol Exploration completed an additional 3 holes to explore the down dip extension of the 903 zone.
