VANCOUVER, British Columbia, Sept. 6, 2012 /PRNewswire/ -- TNR Gold Corp. (the " Company") (TSXV: TNR) is pleased to announce the successful completion of the 2012 exploration drilling and geophysical program on its 100% owned Shotgun Gold Project in Alaska. The 30-day exploration program included 814 metres of drilling in three holes. The geological features observed in the drill core confirm down-dip and along strike extensions of feeder zones discovered in earlier drilling campaigns.
Geophysical surveys that helped to identify the feeder zones were expanded along the ridge and elsewhere within the property during the 2012 work program to guide future drilling.
Drill Program Highlights
Three drill holes totalling 814 metres were completed on the Shotgun Ridge prospect. The drilling was designed to extend the mineralized feeder zones identified in drill hole 06-43 down-dip and along strike. Diamond drill hole 06-43 intersected 210 metres grading 1.3 g/t Au (grams per tonne gold). Higher-grade intervals, within this zone defined the position of structurally controlled feeder zones. The geology, sulphide mineralization and structural features encountered in the 2012 drilling are similar to that found in 06-43. Geochemical assay results are pending.The feeder zone associated with the higher-grade assays in hole 06-43 was intersected in all three drill holes providing the Company with greater confidence in extending this zone along strike and to depth with further drilling. "It is encouraging that we see continuity of the intrusive breccia in all three 2012 drill holes. DDH 12-57 was drilled approximately 50 metres NW of 06-43 and both 12-58 and 12-59 were collared approximately 30 metres behind 06-43, intersecting the targeted zone as much as 100 metres down-dip. These results confirm that the structural feature believed to host some of the better mineralization at Shotgun Ridge is continuous over some distance and correlates well with the ongoing interpretations of the geophysics thus is clearly open at depth." comments John Harrop, VP Exploration. Geophysical anomalies that were interpreted as structural corridors hosting mineralization in the 2011 three-dimensional IP/resistivity survey data were found to be coincident with the interpreted mineralized feeder zones. Additional three-dimensional IP/resistivity surveys were carried out in the 2012 program to expand and further define the correlation between geophysical response and mineralization. Geophysical Survey Highlights Following the successful application of three-dimensional IP/resistivity surveys in 2011, SJ Geophysics Ltd. collected three additional grids during the 2012 field season. One grid was centred on a surface geochemical gold anomaly at the Winchester prospect, the southernmost target area along a 35 kilometres discontinuous mineralized trend running south from Shotgun Ridge. Two other grids were designed to extend the 2011 survey at Shotgun Ridge. The data were collected in a manner where they could be merged with the 2011 surveys and modelled in three dimensions to produce a single comprehensive three-dimensional model of chargeability, resistivity, geology and geochemistry to be used for further target delineation. The geophysical data are being processed and results of the merged surveys are pending.
