Newcastle Chester Property Update

Last Update: 8/11/2011 8:15:36 AM

VICTORIA, BRITISH COLUMBIA, Aug 11, 2011 (Marketwire via COMTEX) -- Newcastle Minerals Ltd. (NCM) is pleased to provide an update on its 100% owned Chester Project located in northwestern Ontario, Canada.

Newcastle completed a preliminary four-hole, 1,050-metre diamond drilling program focusing on targets on the eastern portion of the property in June 2011. While no significant gold assays were returned, anomalous gold was encountered and was dominantly associated with variable degrees of sulfide mineralization, alteration and fracturing in intermediate intrusive (primarily hornblende diorite) and occasionally intermediate-to-mafic metavolcanic rocks. The alteration and fracturing encountered during drilling may be associated with the "Ridout Deformation Zone," which is an important structural element in the area described in Trelawney Mining and Exploration Inc.'s N.I. 43-101 Technical Report on the Cote Lake Deposit. A prospecting and sampling program will commence shortly on the Chester Project.

Also of note is the staking of 12 mineral claims (consisting of 7,680 acres)in June 2011 by Trelawney adjoining Newcastle's 15,480-acre Neville/Potier Project to the north. This places two of Newcastle's projects in the middle of Trelawney's land holdings in the Swayze belt.

Newcastle's President, Michael Romanik, said "We are encouraged by Trelawney's staking to the north of our Neville/Potier Project, validating our focus on the area. With Trelawney's recent takeover bid for Augen Gold, Newcastle's three parcels totaling 17,000 acres adjoining or surrounded by either Trelawney or Augen Gold properties put us in a very strategic position."
