2023 Oropesa Mineral Resource Estimate for Zinc at a 0.05% Zn cut-off (JORC 2012)
A by-product flow sheet recovering and producing a saleable zinc concentrate (~45%Zn) from
a head grade of ~0.5%Zn has been developed
Ore sorting test work at TOMRA laboratories also confirms an average +28% upgrade of zinc
ore feed grades when processed with cassiterite.

•
The zinc is highly correlated with tin mineralisation, resulting in the zinc conceptually being
mined, crushed, ore-sorted, ground at no additional cost to a tin ore only operation.
By-product flow sheet recovers zinc metal from material which would otherwise be sent to
the tailings dam, proving strong environmental stewardship, responsible mining practices and
likely economic benefits.
The incremental capital and operating costs associated with producing zinc are likely to be
relatively minor compared to overall project development costs, creating a strong economic
basis for further zinc by-product assessment.
