Valor Resources (ASX: VAL) has updated the market with high grade copper (Cu) and silver (Ag) intercepts at its Berenguela project located in south-east Peru.
- High grade intercepts including 8m @ 2.95% Cu and 2,161.23 g/t Ag
- 3m interval @ 5.42% Cu and Ag values over 4,000 g/t, exceeding the limits of SGS lab tests.
- BER246: 3 m includes high grade intervals from 66 to 69m, of:
- 66 – 67 m @ 4,761.54 g/t Ag, 5.73% Cu.
- 67 – 68 m @ 5,235.33 g/t Ag, 4.68% Cu.
- 68 – 69 m @ 3,226.00 g/t Ag, 3.97% Cu.
- Full Mineralisation Analysis for BEP029-BER246:
- 16m @ 1.88% Cu + 1,243.31 g/t Ag + 10.43% Mn + 0.39% Zn (from 59m).
- 202% CuEq, including:
- 8 m @ 2.95 Cu% + 2,161.23 Ag g/t + 14.64 Mn% + 0.49 Zn% (from 63m). 13.858% CuEq
Drill hole BER-246 returned several intervals with Ag grades exceeding the lab test limits of 4,000 g/t and further testing was required to obtain the full Ag values. The sample was processed a second time, using gravimetric analysis.
Valor Chairman, Mark Sumner said: “The extraordinarily high copper and silver grades out of drill hole 246 further supports our view that Berenguela is shaping up to be a project of exceptional quality.
The drill program has delivered outstanding results, but the data delivered from drill hole 246 (platform 029) has delineated a high grade zone within the Berenguela deposit. We believe this zone is the focus of the next leg of exploration potential to add to the exciting prospects discovered to date.”
High Grade Copper & Silver Zone
The Berenguela Ag-Cu-Mn deposit comprises several massive west-northwest trending lenses of manganese oxide stocks.
These stockwork bodies are hosted within folded and faulted carbonates, as a network of vuggy veins containing malachite, azurite, covellite, chalcopyrite, chrysocolla, pyrite, and native silver, containing the high Cu and Ag values.
These vuggy veins intrude manganese ores and are associated with the fault and fracture system, where manganese oxides followed by Cu and Ag have replaced dolomitic limestones. These carbonates have been replaced in several cycles of metasomatism to form an irregular ore body elongated along an east-west axis.
The mineralised zones (envelopes of stockwork bodies) have been modelled by a northwest to southeast cross-section, delineating higher grade zones. These zones are based on high Ag and Cu grades, which will be stitched together to produce a 3D model based on the data in Figure 1. Figure 1 shows an example of the mineralised zone (hatched polygon), highlighting the anastomosed high grade (red) Cu and Ag zones.
