KGL Resources Ltd (ASX:KGL) has identified copper mineralised shoots at relatively shallow depth from a 22-hole diamond drilling program at the Reward Deposit within the Jervois Base Metal Project in the Northern Territory.
This program was initiated to increase mineral resource at relatively shallow depth within a 370-metre “gap” between the Reward Main Shoot and the Reward Deeps Shoots, where no high-grade mineralised shoots had been previously modelled.
KGL’s drilling program, completed in 2021, has identified the existence of high-grade shoots in this “gap” from two drillholes:
- KJCD447: 4.471 m (metres) @ 3.81% Cu (copper), 22.0g/t Ag (silver), 0.05 g/t Au (gold) from 176.4m and 4.22m @ 3.18% Cu, 235.8 g/t Ag, 0.27 g/t Au from 195.07m
- KJCD448: 2.57m @ 2.26% Cu, 35.0 g/t Ag, 0.09 g/t Au from 217.9m and 5.16m @ 2.73% Cu, 23.2 g/t Ag, 0.29 g/t Au from 253.0m
Easy access to additional ore
KGL MD Simon Finnis said: “It has become clear through the drilling at Reward we completed in 2021, and the geophysical surveys that were carried out, that there was significant potential for expansion of the known resources at this deposit.
“Along with the updated mineral resource that added 2.3M resource tonnes and 41.3kt of copper metal at Reward this further drilling success gives us optimism there is more to come.
“The further definition of copper mineralised shoots at relatively shallow depth, and outside the currently envisaged mine plan, but in close proximity to areas we do plan to mine, means we’ll have easy access to any additional ore from already developed mining areas, which adds real value at Jervois.”
Next steps
The drilling at Reward Gap has been successful, with most holes intersecting copper of potentially economic grade.
Based on the success of the drilling to date, four additional holes are planned to follow up the intersection in KJCD495.
Success in these new holes will expand the existing Reward Main HW Domain to the north, thus increasing mineral resources in an easily accessible part of the Reward deposit.
Although these expanded resources will not be included in the current feasibility study, it does provide the opportunity to upgrade the study in the future.
Finnis added: “The holes we are currently drilling to the south, and at depth near Reward, also have significant potential for more ore discoveries.”
