Drilling Confirms High-Grade Mineralisation
Pantoro Limited (ASX:PNR) has returned a number of deep high grade intersections from both inside, and outside of the Inferred Mineral Resource envelope from the Scotia Mining Centre in Western Australia.
Drilling at the Scotia Mining Centre, part of the Norseman Gold Project, has been focussed on infilling and expanding the existing Mineral Resource, for conversion to Ore Reserve status.
Infill drilling around and below the historic underground workings at Scotia continues to increase confidence in the ongoing upgrade of Mineral Resource from Inferred to Indicated for subsequent expansion of Ore Reserves.
Managing Director, Paul Cmrlec, said drilling has confirmed two high grade lodes at the deepest level drilled to date which is over 400 metres below surface and remains open.
New deep drilling results include:
- 4 m @ 10.83 g/t Au inc. 0.7 m @ 56.20 g/t Au from 437 m.
- 2.6 m @ 6.51 g/t Au from 451.8 m.
- 5.25 m @ 5.27 g/t Au from 155.75 m.
- 10 m @ 3.18 g/t Au from 177 m.
- 3 m @ 8.12 g/t Au inc. 1 m @ 21.60 g/t Au from 180 m.
- 3.85 m @ 4.03 g/t Au from 446.1 m.
- 9.94 m @ 7.24 g/t Au inc. 1.75m @ 17.38 g/t Au from 195.06 m.
“The Scotia Mining Centre is a key component of the planned recommencement of production at Norseman. Ongoing drilling continues to confirm the growth potential of the Scotia Mining Centre, at depth, through expansion of other existing Mineral Resources, and through new discoveries such as Green Lantern and Panda,” Mr Carle said.
The Scotia Mining Centre is located approximately 25 km south of Norseman and was discovered in 1893. The historic production recorded from the Scotia mine via open pit and underground mining was 811,000 tonnes @ 5.9 g/t Au for 155,000 ounces.
Scotia was actively mined from 1987 until 1996. Mineralisation at Scotia is hosted by a shear zone that transects the Woolyeenyer Formation. The geological environment differs from that at Norseman, in that the stratigraphy has been subjected to higher metamorphic grades.
The Scotia Mining Centre hosts a number of Mineral Resource areas in close proximity, including the dominant Scotia Resource and smaller satellite Resources at Lady Eleanor and Free Gift. The area also includes several zones where high-grade mineral occurrences have not yet been classified within the existing Mineral Resource. Pantoro has an ongoing drilling program utilising multiple drill rigs at Scotia, planned to continue throughout this year.
The Scotia deposit is currently the largest deposit within the Scotia Mining Centre, and drilling has been focussed on infill and extension of the known mineralisation. The current Mineral Resource at the Scotia Mining Centre is estimated to contain 4.15 Mt @ 3.45 g/t Au for 460,000 ounces.
