• All three holes Reverse Circulation (RC) drilled in the
Quirinus Prospect have intersected
copper – silver mineralisation.
• Assay results include:
- 4m @ 1.7% Cu and 13g/t Ag; and
- 6m @ 0.9% Cu and 14g/t Ag, including 2m @ 1.5% Cu and 25g/t Ag.
• These results reinforce the copper-silver prospectivity of the Discovery Metals 6,400 km2, 100% owned tenement package in north west Botswana.
• A diamond drill programme has commenced to enable definition of the intersected
mineralisation.
• The Quirinus prospect contains approximately 40 strike kilometres of potentially copper–silver mineralised stratigraphy.
Discovery Metals Limited (ASX/BSE:”DML”, AIM:”DME”) has announced results from the first three
exploration drill holes into the Quirinus prospect (Figure 1). The Quirinus prospect is located 15 kilometres from the current mineral resources at Zeta, Plutus and Petra in north west Botswana.
Results include 4m @ 1.7% Cu and 13g/t Ag and 6m @ 0.9% Cu and 14g/t Ag including 2m @ 1.5% Cu and 25g/t Ag (Table 1). These three holes were all drilled by the reverse circulation method to a maximum down hole depth of 90 metres. Previous studies of the nearby Zeta, Plutus and Petra Inferred Mineral resources have shown that holes drilled by the reverse circulation method can underestimate the copper grade of the mineralisation.
Surface geochemical sampling has previously defined a 3,300 metre long copper anomaly at Quirinus. The results announced today confirm the presence of potentially economic mineralisation over the 600 metres of this anomaly that has now been drill tested. The prospect remains open along strike to both the northeast and southwest and at depth. Historic geochemical results suggest the anomaly in this portion of the Quirinus prospect could extend to greater than 6,000 metres along strike. A regional soil geochemical survey is being undertaken in this area to better define the lateral extents of this anomaly.
A diamond drilling program similar to those used to define the Zeta, Plutus and Petra Inferred Mineral
resources is also underway at Quirinus to define any potential mineral resource.
Discovery Metals’ Managing Director, Mr. Brad Sampson, said, “To date we have been drilling in areas which will allow us to fast track the development of a significant copper mine at Zeta, Plutus and Petra (Inferred Mineral Resource of 46.1 Mt at 1.3% Cu). We have now successfully taken the knowledge and experience gained during this work into our regional exploration programme and have already identified another very prospective green field area at Quirinus. We believe that these results reinforce the potential for finding further mineralization within Discovery Metals’ entire tenement package in north west Botswana. We know of a number of historic geochemical copper anomalies which have not been drill tested including a number in relatively close proximity to the existing Inferred Mineral resource at Zeta, Plutus and Petra”. “We believe that we are exploring in an emerging and significant copper province”, he said.
