NW zone continued results
The north zone expansion continues west into an area that historical exploration missed, because the limited historical drilling west of the fault back in the day didn’t go deep enough.
The angular drilling approach by Oroco was a clever way to cover a significant amount of both distance and depth beyond the previously measured and indicated resource. You can visually see this in their 3D model data. These results will definitely add tonnage to the project resource estimate and the higher grade near surface will help the NPV calculation earlier in the project life.
Gold and silver are tracking proportionally to copper, which is consistent with other project data that I’ve reviewed. Compare the two holes. As copper concentration doubles, so do gold and silver.
Hole. length Cu (%) Mo (%) Au (g/t) Ag (g/t) CuEq (%)
N044 352.5 0.83 0.011 0.072 6.26 0.93
N045 14.8 0.14 0.002 0.007 1.00 0.15
" 329.8 0.44 0.011 0.035 2.94 0.50
" 28.0 0.15 0.001 0.010 1.08 0.16
Although silver is not included in the calculated CuEq above, it will undoubtably be factored into the PEA because the concentrations are meaningful. Hudbay’s Mason project for example, reported an average 0.029 g/t Au and 0.63 g/t Ag in their measured and indicated 2021 mineral resource estimate. Oroco’s reported assays from 2022 onward are superior to Mason’s in Ag concentration values.
After reviewing the DCIP geophysical survey data more than a year ago, I anticipated any number of upsides to the original historical resource estimate. I am now seeing several of them play out. N044, N045, S020, and S021 are all very good news. The southwest zone exploration flight video on Oroco’s website revealed many areas with blue mineralization (hint: copper). This is all very compelling.
Happy Friday
