Tungsten Mining - Resource Update and High Grade Re-sampling Results
Tungsten Mining Limited (ASX:TGN) has announced the update of resources for Big Hill and Mulgine Hill, acquired from Hazelwood Resources in 2015, to JORC-2012 standard. The updates resulted in slight changes to both tonnages and grade for each deposit, based on different methodology used. Tungsten also announced that it had re-sampled historic core and defined new zones of mineralisation as well as extensions to previous intercepts.
- Mulgine Hill and Big Hill Resources updated to JORC-2012 standard
- Slight changes to tonnages and grade due to different methodology
- Re-sampling of historically drilled core identifies new mineralised zones as well as extensions to intercepts
Emerging Australian tungsten developer, Tungsten Mining NL (ASX: TGN) (“Tungsten Mining” or “the Company”) is pleased to report updated resources for Mulgine Hill, part of the Mt Mulgine Project, located in the Murchison Region of Western Australia and the Big Hill deposit, located in the Pilbara Region.
In December 2015, Tungsten Mining acquired the Mt Mulgine and Big Hill Projects from ATC Alloys Ltd (formerly named Hazelwood Resources Ltd and herein referred to as “Hazelwood”) at a cost of $1.2 million. Mt Mulgine contains two known resources – Mulgine Trench and Mulgine Hill. Big Hill contains a single defined resource.
Tungsten Mining has a third tungsten deposit referred to as Kilba located in the Ashburton region of Western Australia.
Mulgine Trench has previously been reported using JORC-2012 guidelines. However at acquisition, both Mulgine Hill and Big Hill were classified and reported in accordance with JORC-2004 guidelines. The purpose of this announcement is to advise that the Mineral Resource estimates for Mulgine Hill and Big Hill have now been updated in accordance with JORC-2012 guidelines.
Mulgine Hill Core Re-sampling
During April, Tungsten re-sampled various sections of diamond core that were not assayed originally. The zones to be sampled were UV lamped as an initial screen.
The results from the re-sampling exercise included:
· 8.6m @ 0.24% WO3
· 4.9m @ 0.18% WO3
· 2.0m @ 0.14% WO3
These results are considered to provide encouraging indications of the potential to add to existing intersections plus to identify new zones of mineralisation in the Minefields and ANZECO drilling. Sampling of hole DDM195 identified strong mineralisation of 8.6 metres at 0.24% WO3 adjacent to an existing intersection of 4.6 metres at 0.63% WO3. This makes a combined intersection of 13.2 metres at 0.37% WO3. Three other holes returned assays that added to existing intersections (DDM120, DDM140 and DDM189) and two holes located new zones of mineralisation.
There exists 1500 to 2000 metres of core that requires sampling and Tungsten Mining plan to complete this work in the September Quarter.
Planned Work Programme
Tungsten Mining has developed a Strategic Development Plan for the Mt Mulgine Project directed towards the production of tungsten concentrate within 2 years. A staged development approach will be adopted with the initial focus on the Mulgine Hill deposit while concurrently progressing metallurgical test work and development activities on the significantly larger Mulgine Trench deposit.
This strategy aims to produce early cash flow and ensures tungsten production is sustainable long term. Tungsten Mining plans to complete the following work programme in the September Quarter at Mt Mulgine.
- RC drilling targeting shallow mineralisation at Mulgine Hill and Mulgine Trench.
- PQ diamond holes to collect metallurgical samples from Mulgine Hill and Mulgine Trench.
- Metallurgical test work programme to determine a metallurgical treatment pathway of the near surface mineralised material at the Hill deposit and the oxide zone at Trench for a possible extraction methodology.
