Vango Mining Ltd (ASX: VAN) has hit an exceptionally high‐grade gold intersection from drilling at the Mareast prospect on its 100%‐owned Marymia Gold Project WA’s Mid‐West region of WA.
The company’s Executive Chairman Bruce McInnes said Mareast is located at the eastern end of a significant five km structural/mineralisation corridor that continues from the very high‐grade Trident resource through Marwest/Mars prospects to the Mareast prospect.
This thick, high‐grade intersection, 10m @ 22.6 g/t Au from 50m; including 6m @ 33.3 g/t Au; including 4m @ 42.4 g/t Au. was returned from targeted drilling designed to test projected extensions of high‐grade mineralisation mined previously via open pit at Mareast. The new intersection remains open down‐dip and down plunge to the east.
Previous very high‐grade intersections produced by the company below the Mareast pit include: 9m @ 15.0 g/t Au from 28m; including 3m @ 39.8 g/t Au.
These very high‐grade intersections below the Mareast pit are highly significant as they represent the near‐surface expression of a southwest plunging corridor of Mine‐Mafic hosted mineralisation that may continue below Trident, which is situated up to 5km to the southwest,” MrMcInnes said.
“The stratigraphy and structural setting of this corridor is very similar to the >5.5Moz2 Plutonic deposit, located 30km to the southwest.
Targeting of deeper extensions of this very high‐grade Mine‐Mafic hosted mineralisation has highlighted the area between Marwest and Mareast where a thick sequence of mafic rocks (highlighted by gravity inversions) is interpreted to lie below the shallow dipping ultramafic sequence. Deeper RC and possibly diamond drilling is being planned to test this key, larger scale, target area,” he added.
The current, on‐going, drilling programme has included two reverse circulation (RC) holes at Mareast and six holes at the very high‐grade Mars zone, the near surface projection of the 2km strike length of the Trident to Marwest high‐grade gold corridor.
Drilling is now testing the Triple P ‐ Zone B high‐grade resource target, aiming to further define and extend this potentially significant new gold discovery at depth and along strike to the north.
Mr McInness said drilling will aim to extend and scope the high‐grade gold mineralisation into this area, prior to planning follow up, Stage 2, drilling. The Stage 2 drilling will aim to define a new, high‐grade, gold resource to add to the existing Trident high‐grade gold resource base, with the total resource base designed to support the proposed stand‐alone Marymia Gold Project.
