Drilling Results at Vista’s Mt. Todd Project Identify Long Intervals of Gold Mineralization With Higher Grades
DENVER, Nov. 12 /PRNewswire-FirstCall/ -- Vista Gold Corp. (Amex: VGZ; TSX) ("Vista" or the "Company") is pleased to report on the results of six core holes drilled as part of a fourteen-hole 9,006 meter drilling program completed at the Batman Deposit at its Mt. Todd Project in Northern Territory, Australia. The results from the first five holes were reported previously in Vista's press releases dated July 21 and September 3, 2008. Management believes the results confirm the continuity of mineralization extending down-dip from the 2007 drilling results (previously reported in Vista's May 30, 2007 and September 4, 2007 press releases) and demonstrate the same pattern of higher gold grades at depth that contributed to a 65% increase in the measured and indicated resources as reported in Vista's February 27, 2008 press release. Of the fourteen holes completed in this program, one was drilled to obtain a sample for ongoing metallurgical testing (hole VB08-041). Eleven holes were drilled to intersect the untested mineralization down-dip from the 2007 drilling located within the pit shape evaluated as part of the Preliminary Economic Assessment, the results of which were reported in Vista's January 4, 2007 press release. Two holes were drilled to test the continuity of mineralization below the previously evaluated pit shape (holes VB08-039 & -040).
A summary of the gold assay and preliminary copper assay results of the latest six holes are shown below:
Gold Gold Drill Interval Intercept (grams/ Copper Including Intercept (grams/ Copper Hole (meters) (meters) tonne) (ppm) (meters) (meters) tonne) (ppm) VB08032 191-220 29 1.05 356 310-629 319 1.11 582 412-533 121 1.87 717 432-511 79 2.18 841 VB08033 Hole abandoned at 42m and re-collared as VB08034 VB08034 600-621 21 0.68 506 630-706 76 0.77 736 695-706 11 1.64 590 VB08035 281-392 111 0.63 318 430-464 34 1.54 363 417-544 127 1.84 642 475-544 69 2.52 872 VB08036 299-526 227 1.11 549 312-356 44 1.43 746 442-509 67 2.07 747 VB08037 193-245 52 1.54 705 202-234 32 2.00 770 485-601 116 1.37 602Four holes intersected continuous mineralization over 100 meters in length, with hole VB08032 intersecting over 300 meters of continuous mineralization. The same four holes also contained significant (32 to 79 meters) intervals of higher grade material, over 2.0 grams per tonne. All six holes were drilled at an angle to intersect mineralization at close to right angles; however, due to physical constraints and the complex nature of the deposit, true thickness of the drilled intervals cannot be assumed from the measured intercepts.
The drilling program began in April 2008, under the direct supervision of Tim Tuba, Vista's Exploration Manager in Australia, and was completed in September 2008. The core drilling was completed by Boart Longyear Australia Pty Ltd., with the sample preparation being completed by ALS Chemex in Adelaide, South Australia, followed by assaying for gold by ALS Chemex in Perth, Western Australia. A sample quality control/quality assurance program has been implemented and check assaying is being done by Genalysis Laboratory Services Pty Ltd. in Perth. Multi-element analyses, including copper, are being done by ALS Chemex, also in Perth. Sampling and assaying methods were conducted in accordance with the CIM Mineral Exploration Best Practices Guidelines. All samples taken were one meter in length, except the last interval of the drill hole. Frank K. Fenne, P.G., Vice-President of Exploration for Vista, who is a Qualified Person as defined by National Instrument 43-101, has reviewed the program and results and confirms that all protocols used in the project conform to industry standards.
Vista Gold also announces that TetraTech of Golden, Colorado, has been awarded the contract to undertake a preliminary feasibility study on our Mt. Todd Project. TetraTech has partnered with AUSENCO of Perth, Australia, for the process engineering and will be working with Vista's metallurgical consultant, Resource Development Inc. We expect the study to be undertaken in two stages. The first stage has commenced and will include an updated resource estimate, metallurgical testing, rock mechanics evaluations, and preliminary geotechnical and environmental reviews.
Fred Earnest, President & COO of Vista, stated, "This drilling program has accomplished its intended goal and as a result, we expect to see another increase in the measured, indicated and total gold resources for the Mt. Todd Project when the updated resource estimate is completed. The knowledge that we now have about the deep mineralization in the district leads me to believe that future deep drilling below other known surface gold occurrences may identify additional resources. Metallurgical testing has indicated significant opportunities for process improvements and we expect that the ongoing metallurgical test work will result in a flow sheet that addresses many of the principal metallurgical complexities of the deposit. The fact that nearly all of the last two year's drilling has been completed within the pit shape used as the basis for the 2006 Preliminary Economic Assessment indicates that we may see a significant portion of the updated measured and indicated resources converted to reserves when the preliminary feasibility study is completed. We believe this is a significant step forward in establishing the value of this gold deposit."
