Increased Metallurgical recoveries being incorporated into Preliminary Economic Assessment of Turnagain Project

Increased Metallurgical recoveries being incorporated into
Preliminary Economic Assessment of Turnagain Project
(Vancouver) – Martin Vydra, President of Giga Metals Corp. (TSX.V – GIGA) announced today
that recent metallurgical test work has demonstrated significant ly improved nickel and cobalt
recoveries from the Company’s flagship Turnagain deposit.
Ongoing metallurgical test work at Blue Coast Research has identified improvement opportunities
for the straight -forward flotation process used on Turnagain nickel minerals. To date, a
conventional rougher-cleaner flowsheet has been used to recover nickel to a high -grade sulphide
concentrate (15 - 20% Ni).
Recent work has shown that separating the fast -floating nickel minerals from slower -floating
material offers the ability to treat the slower-floating material with a separate conventional flotation
cleaning circuit and/or a concentrate regrind. Repeated tests indicate that this simple change to the
Turnagain mill flowsheet could improve recovery by several percent over the conventional
flowsheet, which has been thoroughly tested.
“The improvement in recoveries is significant enough that we have decided to suspend work on the
Preliminary Economic Assessment ( PEA) while confirmatory metallurgical test work, including
locked-cycle tests, is completed.” said Mr. Vydra. “The new results will be included in the PEA,
and completion is now expected late in the second quarter.”
Giga Metals has been updating the PEA on the Turnagain project to establish the relative value of
the deposit when compared to peer groups of large undeveloped sulphide deposits and
undeveloped, high cost HPAL (High Pressure Acid Leach) laterite projects, both of which are
expected to compete for development dollars to supply the looming demand for battery materials
such as nickel and cobalt.
