Zinco Mining Corporation (TSX VENTURE:ZIM) (FRANKFURT:61Z) is
pleased to announce that it has obtained complete assay results for
955.3 meters of HQ diamond drilling in holes ZIM34 to ZIM42 from
the San Juan prospect, Cuale VMS District, Mexico. Two holes,
drilled 105 meters apart, returned high silver and moderate base
metal values over substantial widths of more than 55 meters down
hole. Hole ZIM35, collared 56 meters west of hole ZIM9, returned
values of 134 g/t silver, 1.2% zinc, 0.78% lead, 0.01% copper and
63 ppb gold across 63 meters. Similar results of 136 g/t silver,
0.75% zinc, 0.49% lead, 0.01% copper and 53 ppb gold across 54.65
meters were returned from ZIM39, collared 70 meters northeast of
ZIM9. Complete results for all of the holes are tabulated
below.
The main objectives of the core drilling program at San Juan
were to: (i) expand on reverse-circulation drill hole intercept
ZIM9 that returned results of 95 g/t silver, 0.96% zinc, 0.44%
lead, 0.01% copper and 56 ppb Au across 194.82 m (the largest
continuous drill hole intercept of silver-rich mineralization ever
intercepted on Zinco's VMS Project), and (ii) model the geological
context of the mineralization, work that could not be done as
reliably with reverse-circulation chip samples.
Overall, the drilling results confirm the following:
-- of 16 holes (both RC and HQ core) drilled at San Juan, 14 holes contain
potentially economic intercepts of silver-rich mineralization,
-- the intercepts occur in an area 280 meters long by 240 meters wide that
remains open to the east and west,
-- 14 of the potentially economic silver-rich intercepts are longer than 14
meters (core-length), and
-- 7 intercepts are longer than 50 meters.
Geologically, silver-rich mineralization at San Juan is hosted in and
peripheral to a quartz-feldspar porhyritic (QFP) rhyolite flow dome complex
that intrudes weakly porphyritic, devitrified rhyolite overlain by
tuffaceous sediments. In detail:
-- The "basement" in the San Juan deposit area consists of weakly quartz-
porphyritic rhyolite with abundant spherulites, lithophysae, perlitic
fractures and other devitrification textures. This unit can contain
sulfide mineralization in vugs caused by devitrification, and in
fractures.
-- The devitrified rhyolite is overlain by normally graded, fining upwards
mass-flow units of rhyolite lapilli tuff to fine tuff, locally with
black argillite and syn-sedimentary pyrite. Massive sulfides can occur
in this unit, generally close to the QFP rhyolite.
-- The basement and the tuffs are intruded by a strongly porphyritic
rhyolite with characteristic dipyramidal quartz as well as feldspar
phenocrysts (QFP). This unit has peperitic (brecciated) boundaries with
the surrounding sediments, a feature that is typical of submarine
rhyolite flow-dome complexes where they intrude unconsolidated
sediments. The upper contact of the QFP with the surrounding sediment is
marked by gossanous zones of semi-massive sulfide a few centimeters to a
few meters thick. Internally, the QFP is marked by abundant microscopic
perlite and spherulites that are preferentially replaced by silver-rich
and base metal sulfides as well as quartz, barite and clay minerals.
Sulfides also occur in randomly oriented stock work veinlets, mainly
without quartz, but commonly marked by clay in vein selvedges. All
silver-rich intercepts longer than 50 meters at San Juan occur in this
QFP.
Overall, the core-drilling program has expanded the bulk-tonnage
silver-lead-zinc potential of San Juan and provided geological
controls on the mineral deposit that will help define the placement
of drill holes for the next drilling program. In particular, on the
basis of these results, the Company intends to conduct further
exploration of the upper and marginal portions of the QFP, the host
rock to the most valuable and silver-rich parts of the San Juan
deposit.
