Scorpio Receives Positive Metallurgical Test Work on the Hoag Zone, Nuestra Senora Silver-Zinc Project


    VANCOUVER, March 13 /CNW/ - Scorpio Mining Corporation (TSX:SPM) is
pleased to report results from the SGS Lakefield's Metallurgical Lab, located
in Lakefield, Ontario, on the metallurgical testing of mineralized material
from the Hoag Zone, Nuestra Senora Silver-Zinc Project.
    Peter J. Hawley, Chairman, CEO reports, "The scoping level metallurgical
test results are very good and indicate clean, high-grade lead and zinc
concentrates. The company is very pleased to see that the Hoag Zone
mineralization is compatible with previous testing on the Nuestra Senora
mineralization. Scorpio Mining Corporation continues to aggressively move
forward in advancing the engineering studies, plant construction and
    The following is the executive summary from their report: "The sample
graded 0.24% Cu, 2.54% Pb, 3.59% Zn and 63.5 g/t Ag. Mineralogical
examinations indicated that moderate amounts of calcite, sphalerite and
grossularite followed by minor amounts of quartz, galena, wurtzite, chlorite,
pyrite, pyroxene and potassium-feldspar were present in the sample. An oxide
copper assay gave no indications of any secondary copper minerals in the
sample that would cause any problems. A Bond ball mill work index test was
completed on this ore and determined to be of average hardness at 14.5 kWh/t."
    "Batch floatation testing found the Hoag material is amenable to the
flowsheet developed for the main Nuestra Senora mineralization, and in fact
produce saleable lead and zinc concentrates with a simpler flowsheet. With the
low copper head grade, a second copper circuit would not be required but is
planned in the current mill flowsheet design."
    "Batch flotation testing found that primary grinding to P80's passing
97 microns, the sphalerite in the sample was 52% liberated, 8% attached and
40% locked with galena, pyrite, chalcopyrite, bornite and covellite. No
regrinds are required. The following results were achieved in the best test
and are presented in Table 1:"

    "The final confirmatory batch cleaner test resulted in a Lead Concentrate
which grading 54.1% Pb, 2.3% Cu, 6.1% Zn and 1,400 g/t Ag recovered 93.10%
lead, 36.10% copper, 6.4% zinc and 78.30% silver from the feed. The
copper/lead cleaner concentrate graded 9.4% Cu, 8.0% lead, 19.1% zinc and
330 g/t Ag while recovering a further 39.0% of Cu, 3.6% Pb, 5.2% Zn and 4.8%
Ag. A zinc cleaner concentrate graded 55.20% Zn, 0.66% Cu and 0.15% Pb while
recovering 71.30% of the zinc, 12.9% of copper and 1.1% of the lead. A full
ICP scan, mercury and gold assays were performed on these products; the
results of the analyses indicate that the combined Pb + Cu/Pb concentrate and
the Zn cleaner concentrate meets most current proforma requirements and should
be easily saleable." (Bond Cromes, M.M.; March 2007).
