Scorpio’s Finds Some RC Drilling Gold

The reverse circulation (RC) drilling method is cheaper and faster than the diamond drill-core drilling method. However, minor contamination between adjacent intervals can sometimes occur with RC drilling.

VANCOUVER, BRITISH COLUMBIA–(Marketwired – Sept. 23, 2013) – Scorpio Gold Corporation (“Scorpio Gold” or the “Company”) (TSX VENTURE:SGN) reports further results from its 2013 satellite deposit drilling program at the 70% owned Mineral Ridge project, located in Nevada.

Below, we have included a map showing the location of the Mineral Ridge project. The project is located approximately 6 km northwest of the town of Silver Peak and 56 km southwest of Tonopah in Esmeralda County, Nevada, USA.

Nevada is richly endowed with gold and is the leading gold-producing state in the United States, producing around 80% of all the gold mined in the nation. Most of the gold in Nevada comes from large open pit mining of low-grade high-tonnage deposits along the Carlin Trend using cyanide heap leaching recovery methods. These deposits are some of the largest hydrothermal gold deposits in the world and is one of the world’s richest gold mining districts.

The first hole drilled in 2013 on the Oromonte deposit followed up on a higher-grade zone of mineralization intersected at depth in 2011-2012 drilling. This hole, MR13599, returned 22.30 g/t over 10.67 m (0.65 oz/ton over 35 ft). Combined with prior drilling, significant grades over substantial widths have now been intersected in four consecutive holes with the mineralization open in three directions.

  • MR13599: 22.30 g/t over 10.67 meters
  • MR12385*: 8.16 g/t over 10.67 meters
  • MR12386*: 1.90 g/t over 6.10 meters
  • MR11142*: 3.84 g/t over 10.67 meters

* Previously reported from prior drill programs.

The indicated zone of mineralization trends northerly and lies along the edge of a geophysical magnetic high. It has been intersected at 85 to 115 metres vertical depth and, although not accessible by open pit mining, may be amenable to underground extraction should further results support underground development. Historical underground workings are known to lie approximately 180 meters to the east. The significance of these drill results in context with their structural and geophysical setting will be evaluated for future follow up.

We have included the drill-hole plan for drilling at the Oromonte deposit. If you look closely there is an error in the labelling of one of the drill-hole collars. The drill-hole collar labelled “MR13385” should probably read “MR12385” to be consistent with the cross-section and the table of results.

We have included the cross-section of the drilling at the Oromonte deposit as it shows the “Mineralized Zone” correlating across the drill-holes.

Keep in mind that this is only one view of the drill-holes intersecting the “Mineralized Zone” at the Oromonte deposit. Depending on the orientation of the plane of the cross-section, the apparent angle and thickness of the “Mineralized Zone” can change. It would be interesting to know where the “Mineralized Zone” outcrops at the surface. If it exists on Scorpio Gold’s property then this would be a real bonus because some mining could then be undertaken by open pit mining methods. Provided of course that it hasn’t already been mined out. For the deeper mineralization an underground development would be more profitable provided that these grades and thicknesses are verified with further drilling.

All holes presented in Table 1 were completed by reverse circulation (“RC”) drilling.

The reverse circulation (RC) drilling method is cheaper and faster than the diamond drill-core drilling method. However, minor contamination between adjacent intervals can sometimes occur with RC drilling, so may provide slightly thicker intersections of mineralized zones than with diamond drill-core drilling. For this reason, diamond drill-core drilling is the preferred method for resource modelling and definition. When logging diamond drill-core, geologists can obtain important information about the structure of rocks, such as the orientation of any faults, veins and shears. This is crucial data when planning an underground mine to ensure its stability. Geologists can also extract information about the texture of the rock and its fabric, which is often destroyed through RC drilling. Metallurgists generally require drill-core to work on when designing the best method for ore extraction. Specific tests such as impact hardness and grindability can be done on drill-core, which cannot be done successfully on rock chips from RC drilling.

True width is estimated at 90-100% of downhole width.

At first glance, it appears that Scorpio Gold’s true width statement might be valid. However, as I mentioned before, the provided cross-section is only one view. More drilling and more cross-sections are needed to obtain the true thickness of the “Mineralized Zone” as there is still a possibility that the drill-holes are intersecting the “Mineralized Zone” at a very oblique angle. If this is indeed so then the “Mineralized Zone” would be much thinner than the reported 10 metres thickness. Read our article for more information about apparent and true thicknesses (widths).

Analytical results were performed by American Assay Laboratory Inc. in Sparks, Nevada, an ISO/IEC 17025:2005 accredited facility. External check assays to verify lab accuracy are completed by ALS Chemex, an ISO 9001:2000 certified and ISO/IEC 17025:2005 accredited facility. Further details are presented in the Company’s quality assurance and quality control program for the Mineral Ridge project at: www.scorpiogold.com/i/pdf/reports/QAQC-MR.pdf.

This is a good idea providing a link to a comprehensive QA/QC program document. A more thorough assessment can be made rather than relying on a brief statement given in a press release. Read our article on QA/QC of geochemical data for some background on the reasoning behind QA/QC programs.
