New Target with High Grade Historic Drilling intercepts
Exploration Status
Target Highlights
- Surface grabs from 2007 highlight values of 807 g/t Au and 2942 g/t Au1
- Historic drilling up to 216.6 g/t Au1
- Surface program planning and preliminary drill planning underway
Project Overview
The BobJo property lies within a structurally complex package of Cycle-III mafic volcanic rocks. From 1928-1929 a shaft was sunk to 270 feet (82m) with approximately 1600 lateral feet (488m) of development established at the 125ft (38m) and 250ft (76m) levels2. Production numbers from the mine total 361.7 ounces of gold and 29 ounces of silver from an unknown tonnage of rock2. Shallow drilling above 400m depth has outlined up to 216.6 g/t Au1. Mineralization at the project is open both along strike and at depth1.
Geological Context
The BobJo project lies adjacent to the contact between the Cycle II and Cycle III volcanics within the Cycle III sequence. Two kilometres to the east, the Grasset, Uchi, Hanalda, and Jalda mine trends have combined historic production of 757,000 tonnes at 5.14 g/t gold2,3. Historic stripping has delineated northwesterly trending gold-bearing veins as in addition to folded veins with westerly trending axial planes subparallel to mineralized shears. Surface grab samples from a mineralized shear zone returned values up to 2942 g/t Au1. The property was drilled in 20071 and 20114 and returned gold values up to 216.6 g/t over 0.3m and 6.1 g/t Au over 0.7m respectively.
The BobJo mineralization occurs along the northerly trending calc-alkaline and tholeiitic basalt contact that strikes subparallel to north-trending regional faulting. A preliminary lithostructural interpretation has been completed that targets high-grade hinge and shear zones of the BobJo Property. A surface work program is being designed across the project to advance towards a maiden drill program.
Next Steps
- Design and implement Greenfield Surface exploration program
- Advance to drill-ready and select maiden drill targets, permit pending.
