Gold exploration and development company Vango Mining Limited (ASX: VAN) has reported the discovery of a new very high‐grade gold zone from the drilling at the Triple‐P target on its Marymia Gold Project in Western Australia.
The company reported that new, very high‐grade gold intersections were identified from drilling below Triple‐P and Zone B pits.
Some of the significant intersections include 4m @ 23.0 g/t Au from 109m incl. 1m @ 85.0 g/t Au; 3m @ 7.79 g/t Au from 124m incl. 1m @ 16.5 g/t Au; 4m @ 9.48 g/t Au from 177m incl. 1m @ 25.0 g/t Au; and 4m @ 6.38 g/t Au from 164m incl. 2m @ 10.9 g/t Au.
The company noted that these intersections represent the discovery of a shallow plunging, high‐grade, gold zone that may continue for over a 1km strike length and remains open to the north and at depth.
Vango said that high‐grade gold mineralisation at Triple‐P is interpreted to be hosted by the Plutonic Mine‐Mafic and is projected to continue west for >2km under shallow‐dipping sedimentary rocks.
This wider target zone is referred to as “Vulcan” and has similar dimensions to the nearby major Plutonic Gold deposit.
The company said that further drilling is planned to extend and further define this exciting new gold discovery and substantially expand the high‐grade gold resource base at Marymia to support a significant, stand‐alone, high‐grade gold mining operation.
Marymia gold project
Vango’s 100%‐owned Marymia gold project is located 300km northeast of Meekatharra in the Mid‐West region of Western Australia.
The company had commenced an initial programme of 10 wide‐spaced reverse circulation (RC) drillholes for 1,900 metres below the Triple‐P and Zone B open pits at Marymia.
The drill program has now lead to the discovery of a new, very high‐grade gold zones.
High-grade intersection from 10 holes
The company reported that all ten holes in the Triple‐P and Zone B drilling intersected gold mineralisation and six holes produced very high‐grade gold intersections.
This includes a bonanza‐grade result of 1m @ 85.0 g/t Au.
Other significant hits at Triple‐P and Zone B includes 3m @ 7.79 g/t Au from 124m incl. 1m @ 16.5 g/t Au; 6m @ 3.16 g/t Au from 103m incl. 1m @ 12.4 g/t Au; 4m @ 9.48 g/t Au from 177m incl. 1m @ 25.0 g/t Au; 4m @ 6.38 g/t Au from 164m incl. 2m @ 10.9 g/t Au; and 2m @ 6.19 g/t Au from 173m incl. 1m @ 10.8 g/t Au.
The company said that these intersections represent the discovery of a shallow plunging, high‐grade, gold zone that may continue for over a 1km strike length and remains open to the north and at depth.
Style of gold mineralization similar to Plutonic deposit
The company said that the Triple‐P and Zone B high‐grade gold mineralisation is a similar style of gold mineralisation to the major Plutonic gold deposit, which has produced >5.5Moz gold produced to date.
Triple‐P and Zone B are hosted by interpreted extensions of the same Mine‐Mafic stratigraphy and, like Plutonic, associated with biotite alteration, silicification (quartz) and sulphide mineralisation (arsenopyrite +/‐ pyrrhotite, pyrite, chalcopyrite).
The company said that the gravity (density) and magnetics inversions indicate that the high‐density Mine‐Mafic unit continues down‐dip to the west of Triple‐P under shallow dipping sedimentary units, but has been periodically thrusted to a shallower position by repeats of the steeply dipping fault structures that control the highgrade gold mineralisation.
Vango noted that this scenario is repeated at Zone B and also at Albatross‐Flamingo and Exocet, over 2km to the west.
The company said that this wider target zone referred to as “Vulcan” has similar dimensions (>2km x >1km) to the Plutonic gold deposit and moving forward will represent a priority exploration and resource development target for Vango.
IP results re-modelled
The company reported that the results from a previous Induced Polarisation (IP) orientation survey have been re‐modelled, highlighting a strong (>30mRads) IP anomaly indicative of sulphide mineralisation at depth and immediately down plunge of the Triple‐P ‐ Zone B high‐grade gold mineralization.
Vango said that further drilling is planned to extend and further define this new, highgrade, gold discovery.
The company expressed confidence that the modelling of geophysics (gravity, magnetics and IP) and further interpretation will continue to generate drilling targets for further testing of this new discovery. The company said that this would make a significant contribution to the Company’s plans to substantially expand the high‐grade gold resource base at Marymia to support a significant, stand‐alone, high‐grade gold mining and processing operation.
