Vancouver, British Columbia CANADA, March 27, 2012 /FSC/ - Gold-Ore Resources Ltd. (GOZ - TSX), announces an updated proven and probable gold reserve estimate for the 100% owned Bjorkdal Gold Mine in Sweden. This new reserve is the first update since the last reported reserve estimate of October 2009 (see News Release dated October 28, 2009), and since that time the Company has completed significant exploration drilling and development.
Highlights are as follows:
* Open pit mineral reserves have increased to 205,696 ounces, net of mine depletion which is a 58% increase;
* Underground reserves have increased to 112,078 ounces, net of mine depletion, which is a 210% increase;
* Proven and probable gold reserves for both the open-pit and underground units of the Bjorkdal mine now total 317,774 ounces, which at current annual production rates represents approximately eight years of mine life, a significant increase from the previous reserve life.
Robert Wasylyshyn, President of Gold-Ore, commented on the expanded reserve base, "We are extremely pleased with this reserve growth and it demonstrates the excellent mine life potential at the Bjorkdal mine. Since production first started at Bjorkdal in 1988, the mine has produced over 1,060,000 ounces of gold. Furthermore, in addition to the reserves there are significant measured and indicated resources outside of the current mine plan. Management is confident that with continued development, these resources will be converted into reserves, thereby extending the mine life further."
Following are the resulting estimated reserves using a gold price of 300 SEK (Swedish Krona) per gram (US$1,395 per ounce):

Open Pit Reserve Parameters
WAI completed a Pit Optimization Study on the open pit resources to estimate open pit reserves. An economic model was generated first and then an ultimate pit was created. A review of the economic parameters yielded economic cut-off grades of 0.39, 0.33 and 0.28 grams/tonne gold, which was used to adjust the ore blocks selected by the model so as to yield more representative ore reserve numbers. The parameters used in the pit optimization runs are detailed below.

Underground Reserve Parameters
Using the WAI's block model for underground resources, Mr. Robert Powers, V.P.- Mining for Gold-Ore, estimated the proven and probable reserves for the underground unit of the mine. Only measured and indicated resources from active mining areas were used to estimate the ore reserves .These areas are well drilled, reasonably well understood geologically, are for the most part un-mined, have accesses in place or planned, and mining methods, mining costs, ground conditions, and metallurgy are all known factors. After receiving and checking the new bounded block model from WAI, a report was generated from the block model for each vein system within the active mine, converting tonnes and grades of un-mined measured and indicated resources to proven and probable reserves, accepting only vein systems above the economic cut-off grade after 80% mining recovery and 30% mining dilution were applied. The costs and parameters used to calculate the economic cut-off grade are tabulated below:

Open Pit & Underground Mineral Resource Estimate
A new resource estimate was compiled in February 2012 by Wardell Armstrong International Ltd. (WAI) from the UK, an independent contractor (see News Release dated March 5, 2012). Data and input parameters were supplied and reviewed by mine site staff and Gold-Ore management. The revised estimate used Datamine software and Ordinary Kriging, and includes the results of 2,147 drill holes. The resource classification is classified in accordance with JORC Code (2004) and the estimate is National Instrument Policy 43-101 compliant. The resource estimates, as previously released on March 5, are as follows:
