SURREY, BRITISH COLUMBIA-(Marketwire -10/11/11)-
Zinco Mining Corporation (TSX-V: ZIM.V - News) (Frankfurt: 61Z.F - News) 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 andperipheral to a quartz-feldspar porhyritic (QFP) rhyolite flow dome complexthat intrudes weakly porphyritic, devitrified rhyolite overlain bytuffaceous 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.
