RE:RE:RE:RE:RE:RE:Comparing GSE vs. CYP Both CYP and NZN are oxide zinc deposits. But how big of a problem it is? I took a look
at Zincore metals PFS for their oxide zinc deposit. It's 10m tonnes open pit with 7.5%
Zn&Pb. $350m capex seems to be the problem, they need $1.28/lb Zinc to be modestly
feasible (20% IRR).
Currently NZN has 200x150x40x2.3 = 2.8m tonnes of similar grades, but with 100m
overburden.
CYP, I could not figure out the approximate size of their mineralization. I bet it's
very small with all the drill holes close each other.
From NZN news release:
"All zinc-lead mineralization intersected to-date is non-sulphide (smithsonite,
zincite, and hydrozincite) in nature to the depths drilled and is currently known to
extend to depths of 200 metres vertically. While non-sulphide zinc deposits were
historically the primary source of zinc metal for the world, the last several decades
have been dominated by sulphide (sphalerite) zinc deposit mining. Recent advances in
hydro-metallurgy and leach technology along with a general lack of new sulphide zinc
deposits is bringing non-sulphide zinc deposits back into focus as sought after
exploration targets.
Examples of non-sulphide zinc deposits include the Skorpion zinc deposit in Namibia
currently being mined by Vedanta and the Vazante zinc deposit in Brazil being mined by
Votarantim."
