Excellon intersects 55 metres of source-style mineralization 1.1 km northwest of Platosa Mine

Toronto Stock Exchange - EXN

132 g/t (3.8 oz/T) Silver; 3.1% Lead, 1.7% Zinc over 55 metres Including 264 g/t (7.7 oz/T) Silver; 10.4% Lead, 7.5% Zinc over 3.2 metres

Platosa Exploration Highlights:

  • Hole LP1019 has encountered several intervals of semi-massive to massive sulphides within 55.46 m of pyroxene and garnet-rich skarn at Rincon del Caido, 1.1 km northwest of the Platosa Mine.  The skarn occurs at a marble-hornfels contact and the entire 55.46 m runs 132 g/t Ag, 3.13% Pb, 1.74% Zn and 0.075 g/t Au;
  • Five strongly mineralized intervals have been identified within the 55.46 m.  Two of these run 336 g/t Ag, 3.27% Pb, 1.96% Zn and 0.240 g/t Au over 4.10 m and 264 g/t Ag, 10.41% Pb, 7.59% Zn and 0.041 g/t Au over 3.27 m respectively;
  • This is the first time persistently anomalous gold has been intersected at Platosa;
  • This discovery clearly suggests increasing proximity to the Source of the high-grade Platosa mantos;
  • Comparison with similar deposits in Mexico suggests mineralization should be traceable between the Platosa Mine and this new area;
  • A third drill has been mobilized to the site and three rigs are now deployed at Rincon del Caido

TORONTO, July 9, 2012 /CNW/ - Excellon Resources Inc. (TSX:EXN) ("Excellon" or "the Company") Mexico's highest grade silver producer, is pleased to report results for hole EX12LP-1019 drilled in the Rincon del Caido area adjacent to previously reported holes LP986 and LP1008, both of which encountered encouraging "Source"-type geology and sulphide mineralization.

Hole LP1019 encountered several important sulphide intervals between 516.70 m and 604.00 m down hole, with the bulk of the mineralization found between 516.70 m and 572.16 m.  All the mineralization is hosted by a pyroxene and garnet-rich skarn located either at or near a marble-hornfels contact.  The hole bottomed in a granitic intrusive at 914 m depth.

John Sullivan, Vice-President of Exploration states; "Management believes that Hole LP 1019 provides the clearest evidence to date that we are now in a Source environment and are getting closer to the large-tonnage CRD/Source that has been the ultimate object of the Company's exploration program since it acquired the Platosa property in 1996."  He further noted: "Hole LP1019 displays the style and magnitude of near-Source mineralization that we have anticipated for some time.  The exploration team has collected and pieced together the pieces of the highly complicated Platosa geotechnical puzzle and we are delighted that their patience and diligence have again paid off with an important discovery."

The mineralization shows multiple stages of development with the pyrite-rich semi-massive to massive portions, which resemble the sulphides being mined from the Platosa mantos, clearly overprinting earlier garnet and pyroxene skarn. Company geologists believe the high lead content, consistently anomalous gold values and skarn mineralogy indicate that this area is still somewhat distal to the Source itself, but may lie along the feeder system that leads to the Source.  The Source may lie between Rincon del Caido and the high-grade Platosa mantos presently being mined, or farther to the northwest.  Given the volume of mineralization, and its high pyrite content, the Company plans to carry out downhole geophysical surveying in mid-July to determine if vectors can be discerned to guide additional drilling.  In the meantime all three on-site exploration drills are concentrated at Rincon del Caido. 

Assays for the hole LP1019 intersections, with the exception of the interval from 602 m to 604 m where assays remain pending, are found in the table below and Rincon del Caido hole locations are shown on Map 2.  Map 3 is a composite cross-section showing holes LP763, LP986, LP1008 and LP1019.  The intervals mentioned in this press release are core widths.  Mineralization banding lies at a high angle to the core axis, but more geometric information is required to confidently estimate true thicknesses.

Since the exploration press release dated May 30, 2012 three other holes in addition to hole LP1019 have been drilled at Platosa.  One was abandoned prior to target depth because of technical problems.  All encountered minor sulphides, but none intersected metal values of significance.

Mexican drill core samples are prepared and assayed by SGS Minerals Services ("SGS") in Durango, Mexico.  The lab is accredited to ISO/IEC 17025.  The Company has a comprehensive QAQC program, supervised by an independent Qualified Person.
