Excellon Resources Inc.: Provides Operational Update

TORONTO, 06/17/10 - Excellon Resources Inc. (TSX: EXN) wishes to provide, in advance of the upcoming Annual General Meeting on Friday June 18th, 2010, an update on several important initiatives as follows:

Platosa continues to produce consistent volumes in excess of the 2010 mining plan. Year to date the mine has produced above the planned 200 tonnes per day due to the application of disciplined mining methods and the effective control of water inflows. The Company will provide a formal 2010 guidance update with the second quarter results due in August but management expects this favourable volume trend to continue.

Excellon is developing a mining plan, that management estimates, will allow Platosa to expand production in 2011 and has begun planning for this expansion. The capital cost will be minimal; it includes the construction of a new fresh air raise, and incremental mine development. The three water-control doors have been constructed, one has been installed and tested successfully, and the other two are on-site awaiting installation. Other water-control measures are being developed in collaboration with the Denver-based hydrology consultants. Additional mining equipment in support of this expansion is en route to Mexico after undergoing final manufacturing modifications in Canada. This equipment has been paid for out of existing cash flow. The Mexican operations currently have more than adequate crushing and milling capacity to accommodate a substantial increase in production.

In spite of these high degrees of activity and investment the company held cash resources of $7million as at May 31, 2010.

'We are pleased with the continued progress that Excellon has been able to deliver on the many exciting initiatives that the company is pursuing,' stated Peter Crossgrove, Excellon's Chairman and CEO. 'The Company is a unique junior company in that it holds a large portfolio of growth opportunities and the cash to fund them internally.'
