Skeena Reports Copper & PGM Assays From Tropico Drilling, Mexico

Marketwired Canada
Skeena Resources Limited (TSX VENTURE:SKE) is pleased to announce assay results
of the first 8 holes from its current 5,000 metre diamond drill program on its
100% owned Tropico Project, Sinaloa State, Mexico. Encouraging results have been
obtained from 11 of the 12 holes completed to date (totaling 2,800 m), out of a
proposed 22 hole first phase program, on this layered mafic/ultramafic complex.
Within the central portion of the Maricela - San Pablo Zone (refer to news
release dated May 10, 2011), up to four parallel 16 metre to greater than 60
metre thick horizons of mineralized pyroxenite, interspersed with barren gabbro,
have been drill intersected, each yielding 0.2 to 0.5 % copper, from 0.2 g/t to
0.6 g/t PGM (platinum + palladium + gold) and an average silver content of 2
g/t. The 2 pyroxenite bands on the north side appear to have good continuity
over a strike length of at least 2.5 km; the 2 horizons on the south side are
less well investigated at this stage but are interpreted to have continuity over
a strike length of at least 1.5 km.
Assay results are set out in the Table below, and the reader is referred to a
drill plan map on the Company's website at

(i) Mineralization remains open at depth as the hole was stopped short
(ii) Mineralization remains open at depth as additional assays are pending
The layered complex hosting both northern and southern horizons appears to dip
vertically to steeply north. However, there is insufficient information to
determine true thicknesses of the mineralized intercepts, which in all
likelihood will be slightly less than the apparent lengths here reported. All of
the holes to date have been drilled at -45 degrees.
Additional drilling will test for the lateral continuity of several historic
'gaps' along the Maricela - San Pablo Zone. Also, several short shallow holes
will be drilled to complete cross sections of the complex with a specific goal
of testing the basal contact of the lower pyroxenite, such as beneath
cross-section SK11-001 and SK11-002 and beneath cross-section SK11-007 and
SK11-008.
Further drill results will be reported in batches of holes.
Quality Control
The technical information in this news release has been prepared in accordance
with Canadian regulatory requirements set out in National Instrument 43-101 and
reviewed by Rupert Allan, P.Geol., president and CEO of Skeena Resources
Limited, the designated Qualified Person for this project. On site drilling
supervision is provided by two independent geologists, Dr. Daniel Rubiolo of
GeoServa Exploration Ltd. and Ing. Felipe Ortega Garcia of Servicios Geologicos
y Mineros de-Aztlan SA de CV. A rigorous chain-of-custody and QA/QC program,
consisting of the insertion of certified standard control samples, duplicates
and blanks was applied to the N thin-walled diameter, sawn half-core samples.
Sample preparation was handled by an Acme Analytical Laboratories facility in
Guadalajara, Mexico and the analyses by Acme Analytical in Vancouver, British
Columbia. Gold and the PGM elements are analyzed by fire assay with an ICP-ES
finish, and 31 additional elements by ICP-AES analyses. Drill intercepts are
reported as down hole lengths over widths in metres, as true widths of the
various zones have not yet been reliably ascertained.
