Excellon announces the discovery of rare earth elements at Platosa

TORONTO, ONTARIO–(Marketwire – Sept. 27, 2011) – Excellon Resources Inc. (TSX:EXN) is pleased to announce the discovery of anomalous Rare Earth Element (REE) values in four drill holes located six kilometres north-northwest of the Platosa Mine. Values of Total Rare Earth Element Oxides (TREEO), the manner in which REE content is normally reported, range from 1,308 ppm (0.131%) TREEO over a 36.25 m core width in hole EX06-JVN03 to 2,136 ppm (0.214%) TREEO over a 281.25 m core width in hole EX06-JVN04. The TREEO amounts are comprised of Cerium, Dysprosium, Lanthanum, Neodymium, Praseodymium, Samarium and Yttrium oxides. Values of other REE oxides have been encountered but are not included in the reported results. Not enough is known about the occurrence to enable Company geologists to estimate true widths at this time. Assays for the four holes are shown in the table below.

The four holes were drilled into a lightly-sulphidized 400 by 400 m, irregularly-shaped and outcropping rhyolite breccia in the Cañón Colorado area during the course of one of the Company’s carbonate replacement deposit (CRD) exploration programs in 2006 and the analytical package used was understandably designed for silver, lead, zinc, and associated elements, not REE exploration, although the package did include Yttrium (Y). While Y is not an REE, it is commonly found with REEs and typically grouped with them for discussion purposes. During the course of reviewing historic data and field examinations of certain prospective CRD areas earlier in 2011, Company geologists encountered anomalous Y values in surface samples and this led them back to the Cañón Colorado area and to resampling the preserved drill core from the 2006 program. Previously sampled core was quarter split and several hundred metres of previously unsampled core was split and a total of 594 samples were sent to the ALS Chemex sample preparation facility in Chihuahua City. Sample pulps were shipped to the ALS Chemex laboratory in North Vancouver, British Columbia, where they were analyzed for 33 elements, including all the REEs plus Yttrium using an inductively coupled plasma (ICP) method.

The Cañón Colorado area lies on Excellon mining concessions and is part of the 58,000 ha Platosa Property where the high-grade Platosa Ag, Pb, Zn mine has been in production since mid-2005. The Company has recently signed a five-year surface rights access agreement covering a 1,000 ha area centred on Cañón Colorado, with El Ejido Puerto de Jaboncillo (Ejido). The Cañón Colorado area is shown on Map 2 below.

“We are very encouraged by this REE discovery and the surface rights agreement with the Ejido,” said John Sullivan, Excellon’s Vice-President of Exploration. “We intend to begin a mapping and prospecting program by early October and carry out additional diamond drilling before year end. Should these drilling results continue to be promising, we would then be in a position to undertake more advanced work such as metallurgical studies.”
