Razorback Iron Ore Project
The Razorback and Iron Peak deposits have negligible overburden (part of the resource outcrops) which is conducive to lower strip ratios and mining costs. In the interim economic update released to the ASX in June 2023, Magnetite Mines estimated a Life-Of-Mine strip ratio of 0.35 for a 91-year, 5Mtpa development at Razorback.
