The Tallangallook Project includes the Golden Mountain gold deposit, which is a granite related gold skarn located within the hornfels zone of the Strathbogie granite. Tallangallook is located 24km north of Bonnie Doon and 32km NW of Mansfield in Victoria, Australia. Mansfield is 189km north east of Melbourne.
The project is held through an Exploration Licence EL006430.
Outline of the proposed program of work and community engagement.
The company’s main area of work will be at the Golden Mountain prospect at Tallangallook. Here the exploration work will include;
- Desktop studies and research,
- Land access negotiations,
- GPS mapping and reconnaissance
- Surface sampling using hand tools
- Grid based and control point surveying
- Work Plan approval for drilling and/or trenching
- Possibly drilling and/or trenching
A Work Plan is required under the Mineral Resources Development Act, which is monitored by the Department of Economic Development (DEDJTR) for intrusive exploration work, such as drilling. The Work Plan has specific drilling information about locations, access, restrictions and risks. It needs to be approved by the various government authorities prior to any works being carried out. In particular, the Crown Land manager (DELWP) is required to approve the Work Plan on Crown Land.
A Bond is held by DEDJTR prior to the Work Plan activities taking place, to ensure that any necessary rehabilitation after drilling is carried out. The level of the Bond is set by the DEDJTR and according to the level of activity presented in the Work Plan.
Other satellite gold prospects within the licence will be reviewed and if the available information is encouraging the landowner or land manager will be contacted in person for discussion and access negotiations. Initial assessment of these various minor prospects will be a similar iterative process to that listed above and include research, access, surface sampling, mapping and surveying.
Prospects located on private property and deemed worthy of further exploration will require an approved Work Plan to allow drilling or trenching, which will also require a Landowner Agreement. Landowner Agreements are designed to compensate the landowner for the disturbance caused by drilling or trenching. Discussions of the Work Plan will be held with the landowner prior to carrying out such work.
All site disturbances must be rehabilitated after the drilling program has been completed. It is in the best interest of our company to keep the intrusive disturbance of the landscape to a minimum, which is in line with all associated parties.
In terms of drilling techniques, there are essentially two types used in mineral exploration, known as;
- Percussion drilling
- Diamond drilling
Percussion drilling uses compressed air and a percussive mechanism to smash the rock as it drills and is limited to drilling depths of around 150 meters. It produces a crushed rock sample from the drill hole and is quite rapid and therefore very cost effective. A percussion drilling rig can do about 100 to 150 meters per day. A percussion drill rig is usually either truck mounted or track mounted and large compressors are necessary.
Diamond drilling is uses high speed rotation, water and diamond tipped drill bits to produce a core sample (like an apple corer). It can drill down beyond 1km and usually drills about 20 meters per day. It is therefore very expensive compared to percussion drilling but a better quality sample of whole rock is received, which can be used for more detailed studies. Diamond drilling rigs can be quite small, skid mounted and even man portable.
