Belo Sun Mining Corp. (TSX VENTURE:BSX) has announced the results of 7 additional drill holes from the diamond drilling program at the Volta Grande Gold Project located in Para State, Brazil.
Results from three drill holes from the Grota Seca deposit extend the near surface mineralization. Hole VVGD-024 intersected 33.00 meters grading 1.88 g/t Au, including 14.70 meters grading 3.32 g/t Au. This relatively high grade zone is located at only 100 meters below surface with excellent potential to be further extended down dip (see section GS 800 W attached). Hole VVGD-032 located on section GS 850 W also intersected multiple mineralized zones at depths of around 120 meters below surface which includes: 15.30 meters grading 2.48 g/t Au, including 4.24 meters grading 7.16 g/t Au and 23.08 meters grading 1.97 g/t Au, including 8.21 meters grading 4.22 g/t Au.
Results from the drilling at the Ouro Verde deposit confirm that the mineralization is continuous to at least 350 m below surface. Hole VVGD – 028 for instance, intersected 26.90 meters grading 2.76 g/t Au, including 13.86 meters grading 4.48 g/t Au. Work is ongoing to determine the structural control of these higher grade zones and the Company believes that better understanding of the structural controls will allow it to further optimize the efficiency of the program. Mining trade-off studies will be carried out in order to demonstrate the economic viability to mine this ore underground below the planned open pit
Belo Sun has completed approximately 11,000 meters (40 holes) of the currently planned 15,000 meter program; 20 drill holes are from the Ouro Verde Deposit, five from the Gameleira Target, and fifteen from the Grota Seca Deposit. Assays are not yet available for eleven of these holes for which the samples are already in the Lab. The drilling program is succeeding in upgrading the existing mineral resource estimate and in delineating extensions of the deposits along strike and down dip.
In addition to the drilling, Belo Sun is completing a 50 line-km soil grid on the "South Block" target and an induced-polarization (IP) survey. This target extends approximately 7 kilometers along strike within a sheared diorite intrusion and is located 5 kilometers southeast of the Grota Seca deposit in an area with numerous garimpos (artisanal gold mine workings) and results from rock sampling around Itatá garimpo returned up to 15.6 g/t Au. A diamond drill campaign will target this highly prospective area once results of the geochemical and geophysical surveys are interpreted.
Helio Diniz, the Vice President, Exploration for Belo Sun, stated "Our level of confidence in the expansion of the resources is increasing with the progress of the current drilling program. It is very encouraging that there are strong indications that the multiple mineralized zones could be extended considerably along strike in both directions as well as down dip with further drilling. It is also particularly significant that the initial deep drilling at Ouro Verde Deposit demonstrates the continuity of these multiple zones down dip. "
Quality Assurance and Quality Control
The scientific and technical information in this press release has been reviewed and approved by David Gower, P. Geo., an advisor to Belo Sun and a Qualified Person as defined by National Instrument 43-101. The exploration program is directly supervised by Mr. Carlos Cravo, Belo Sun's exploration manager. Belo Sun's procedures for handling drill core comprise initial description and logging into a Microsoft Access database. Mineralized and suspected mineralized intervals in the drill holes are described in detail and marked for sampling. Core is then cut in half with the right-hand portion of the core put into plastic sample bags and sealed. The left-hand portion is returned to the core box and is stored for future reference or study. Assay standard and "Blank" samples are inserted every 20th sample. These samples are then delivered to ACME Labs sample preparation facility in Itaituba, Para, Brazil. The assay samples are then fine-crushed to better than 85% passing 10 mesh screen, with an assay pulp split of up to 500 grams pulverized to better than 85% passing 200 mesh screen. Samples are assayed at ACME Labs in Santiago, Chile, using a 50 gram fire assay with AAS finish. These QA/QC procedures provide several measures of data quality and assure the Company that the assay data is representative of the original sample.
