Some good info regarding Operations & Infrastructure required:
3 Mining Methodology:
Alien proposes to mine the deposits using conventional surface mining machines. It is anticipated that
mining activities will initially focus on the Western Ridges (Ridge C and Ridge E), which contains over
2 years of mining material.
No pit dewatering is anticipated for this initial stage of works.
Ore will be crushed and screened prior to transport to port. Waste material will be stored within a waste
rock landform.
Mining will be carried out by contractors in line with Alien’s current mining strategy and presents a low risk option. The mining contractor will be selected and engaged by Alien through a competitive tender
process. It is likely that mining will occur over two 12-hour shifts.
4 Ore Processing and Transport
The Project is based on a 2.6Mtpa processing strategy and an eight (8) year mine life. No on-site fixed
plant processing is required. Screening and crushing will be completed by a mobile unit at the mine
face. A haul road between the mine and the stockpile and loadout area at Great Northern Highway will
be constructed. Road transport will be utilized for the delivery of ore to Port Hedland.
The design philosophy will be based on providing a cost-effective processing solution, while maintaining
high levels of reliability, operability, and maintainability.
