The Hackett River silver-zinc property (Sabina Silver Corporation) hosts at least eight known massive
sulphide occurrences; the most significant are East Cleaver, Boot Lake, and the Main zone (also
called “A” zone), with other important showings being the Knob Hill, Downie, Finger Lake and Jo
zones. The property covers nine mining leases with an aggregate area of 12 250 ha. Hackett River
(75 km south-southwest of Bathurst Inlet) is one of the largest undeveloped massive sulphide
deposits in Canada.
Sabina recently expanded the indicated resources to 205 million oz of silver and 4.3 billion lb of
zinc, with 305 Mlb of copper, 644 Mlb of lead, and 433 000 oz of gold (above a 5.0 oz/ton silverequivalent
grade cut-off). This new resource estimate is based on 300 drill holes with an aggregate
length of 63 745 m. The company has also retained Wardrop Engineering to develop a preliminary
economic assessment based on the strength of these new estimates.
Sabina had significant results from its 2006 drill program. The highlight was the partial delineation
of a new discovery called the “Boot Lake Deep” trough. The structure contains true-width drill
intercepts up to 50 m wide grading 12% zinc and 300 g/t silver. A total of 17 293 m (53 holes) were
drilled as both in-fill and step-out work as all three main deposits remain open. In a recent deep
step-out hole at Boot Lake, assays included 42.95 m of 8.35% zinc and 180.5 g/t silver with a
second hole containing 49.85 m of 9.18% zinc and 141.6 g/t silver.
All deposits and showings are located at approximately the same stratigraphic interval and occur
over a 6-km-long strike length. The East Cleaver, Boot Lake and Main zone deposits are hosted
within a Mineral Horizon Member characterized by the presence of marble and/or calc-silicate,
chert, and variable quantities of sulphides. Mineralization in each of the three massive sulphide
deposits consists primarily of coarse-grained pyrite, pyrrhotite, sphalerite, chalcopyrite, galena, and rare tetrahedrite and trace arsenopyrite. The Boot Lake, Finger Lake, Main zone and Jo zone
deposits and showings are hosted within a southward-dipping stratigraphic sequence. The Knob Hill
zone and East Cleaver deposit are found within an overturned anticline that plunges steeply to the
west.
