Zinco Drilling Intercepts 202.98 Metres Of 92 G/T Silver At The San Juan Deposit, Cuale Vms Camp, Jalisco, Mexico

 Zinco Mining Corporation ("Zinco") reports that it has received and interpreted the remaining San Juan deposit assay results for drill holes ZIM 1 though ZIM 14, all holes drilled into San Juan and other targets on the Mesa de La Descubriadora during the recently completed reverse circulation drilling campaign on the Company's 100% owned mining licenses in the Cuale VMS camp near Puerto Vallarta, Jalisco Mexico. Results for Holes ZIM3 and 4 were released in August of 2008 (NR 2008.07). Assay results are still pending from a further 19 holes drilled into the Jesus Maria deposits and other targets during the spring drilling campaign.

Highlights

The highlight of the drilling at San Juan is hole ZIM 9 which was collared 42 metres west southwest ZIM 3 and 4 and drilled northerly at -58 degrees. The entire hole was mineralized to a depth of 202.98 metres (658 feet). Average metal values across the entire length are 92 g/t silver (2.7 opt), 0.93% zinc, 0.43% lead and 58 ppb gold. Within this intercept, there is a higher grade interval of 377 g/t silver (11.0 opt), 3.25% zinc, 1.60% lead, 0.02% copper and 48 ppb gold across 23.46 metres (77 feet) between 54.06 and 77.52 metres down hole. Other significant intercepts of silver and base metal mineralization were intersected in several holes (Table 1).

Management is encouraged by the wide spatial distribution of polymetallic mineralization encountered in the San Juan area and by the presence of significant intersections of potentially economic grade material. Zinco's San Juan deposit drilling, particularly hole Zim 9, has returned assay results similar to intercepts from bulk tonnage polymetallic deposits such as Penasquito ( Goldcorp, Zacatecas), San Cristobal (Apex Silver, Bolivia) and Santa Ana (Bear Creek, Peru)."

Geological interpretation of the drill results indicates that San Juan is a precious metal-enriched VMS deposit that occurs where a west-northwesterly trending structure (elongate alteration pipe) cross-cuts a perlitic-fractured, spherulitic rhyolite flow-dome. The structure is marked by strong talc and sericite alteration, as well as the highest metal values. Mineralization is also localized at or near the contact of the dome with an overlying tuffaceous sedimentary unit (e.g. intercepts in holes ZIM 1, 5 and 2). Chlorite-sericite alteration occurs peripheral to- and beneath the ore-grade, talc-sericite zones.

Zinco's recently completed exploration drilling has delineated a body of mineralized rock with a strike length of about 220 metres, a width of 110 metres and a variable depth of 100 to 200 metres that remains open to the west-northwest. A major implication of this drilling is that San Juan appears to be the largest discovery in the Cuale District. Further drilling is planned to delineate the rest of the San Juan ore body and provide an initial resource estimate.

The new drill hole data were used in conjunction with Zinco's other exploration datasets, including a 3-D magnetic model created by SJ Geophysics, to constrain and develop geological models for other mineral deposits on La Mesa de la Descubriadora. One of the important results of the analysis is that past producer Grandeza might be part of a more extensive mineralized horizon that crops out mainly between 2000 and 2100 metres elevation, or about 160 metres above the San Juan horizon, which occurs mainly between 1840 and 16 40 metres elevation. Historic production from the Grandeza open pit was 756 661 tonnes of 1.89 g/t Au (0.06 opt), 22 g/t Ag (0.64 opt), 1.41% Pb, 2.35% Zn and 0.2% Cu. Further drilling is planned to investigate the bulk tonnage, polymetallic potential of new targets defined by this new analysis.

Qualified Person/Analytical Procedures

Information contained in this announcement has been reviewed by Michelle Robinson (MASc., P.Eng), Director of Zinco Mining Corporation. Ms. Robinson has 16 years experience in base metals exploration and geochemistry and is the Qualified Person in charge of Zinco's exploration programs.

Reverse circulation drill cuttings were collected at 1.02-metre intervals, and a 1 to 2 kilogram split was prepared using either dry or wet splitting methods at the drill site. Blind standard and blank sample pulps were inserted into the sample stream for analytical control. The splits for assay were securely packaged and sent via Transportes Castores to ACME Analytical Laboratories Mexico S.A. de C.V. in Guadalajara, Jalisco, Mexico for sample preparation. Back-up samples were X-rayed using a handheld Niton XRF analyzer then stored on-site. At ACME's preparation lab, the samples were crushed and pulverized to 200 mesh, and prepared pulps were couriered via DHL Express to ACME Analytical Laboratories Ltd. at 1020 Cordova St. East, Vancouver, B.C. V6A 4A3, Canada. Thirty gram splits were assayed for gold using fire assay fusion Au followed by ICP-ES. Base metals, silver and other trace and major elements were analyzed using 0.5 grams of pulp in a 4 acid digestion and combined ICP-ES and ICP-MS methods.
