I thought I would do quick post on my latest thoughts on Eloro Resources. For some background you can find my initial piece on the company HERE.
Eloro Resources came out with the first assays from Iska Iska on November 18: LINK
The first assays were no barn burners but showed that there was potentially low grade, bulk minable stuff in the first breccia pipe:
“Number of extensive mineralized intersections in holes within major breccia pipe including54.48 g Ag/t, 1.45% Zinc (Zn) and 1.60% Lead (Pb) over 16.39m (140.91 g Ag eq/t) within a broader interval of 122.74m grading 14.29 g Ag/t, 0.81% Zn and 0.41% Pb (53.67 g Ag/t eq) in Hole DHK-04;”
I haven’t run the economic value numbers but I remember this snippet from Bob Moriarty’s piece on Eloro Resources:
“The company has taken underground channel samples that are simply absurd, measuring Silver 35.5 – 694 g/t, Gold 0.31 – 28.6 g/t Au, Zinc 1.05 – 16.95% Zn and Lead 0.41 – 16.95% Pb. If you took the worst of each of those samples for each element it would be $67 a ton rock. In Bolivia that is economic.”
Other snippets from the news release were as follows:
High Grade Gold-Bismuth zone averages 7.1 g Au/t and 0.2% Bi (8.29 g Au eq/t) over 3.04m width for strike length of 47m in underground workings and is open along strike to the north.
6.51g Au/t, 0.07% Bi and 31.96 g Ag/t (7.68 g Au eq/t) over 11.85m grading including 29.56 g Au/t,0.26% Bi/t and 63.69 g Ag/t (31.94 g Au eq/t) over 2.31m intersected in Hole DHK-05 on the strike extension of the high-grade Au-Bi zone.
What is probably even more interesting was the information in the news release that followed on November 24: LINK
Drill Hole DHK-14 drilled at -10 degrees to the southwest of Huayra Kasa workings from Drill Bay #3 intersected almost 180m of silicified and mineralized breccia in the Santa Barbara Breccia Pipe. Hole ended in well-mineralized breccia once the drill reached its depth capacity and only penetrated approximately 50% of the breccia pipe.
Channel sampling in 2019 at the north-western end of the Santa Barbara adit returned 0.32 g Au/t, 26.90 g Ag/t, 1.16% Pb, 28.5 g In/t and > 500ppm Sn along the margin of this pipe.
A third potential breccia pipe immediately to the south, the Central Breccia Pipe, identified by surface geological mapping and Aster satellite data, is elongate in shape with potential dimensions of approximately 400m by 700m;
Five (5) additional potential breccia pipe targets outlined further to the south and east; all confirmed and potential breccia pipes occur along ring structures in the margins of the Iska Iska caldera complex.
… So hole DHK-14 went straight into what looks to be a much larger breccia pipe (The Santa Barbara Breccia Pipe):
Further description of the hole:
“Drill Hole DHK-14 drilled at -10 degrees to the southwest of the underground workings from Drill Bay #3 intersected almost 180m of silicified and mineralized breccia from 151m to 330m in the Santa Barbara Breccia Pipe. This hole stopped in well-mineralized breccia at the maximum limit of the drilling range and only penetrated approximately 50% of the breccia pipe. Assays are pending. A field XRF analyser indicates the presence of lead (Pb) and zinc (Zn) predominantly before and in the periphery of the breccia transitioning to copper (Cu), bismuth (Bi) and tin (Sn) in the central part. However, the numbers measured are not quantitatively accurate hence cannot be reported. Note that silver (Ag) and gold (Au) cannot be detected by this instrument.”
Iska Iska surely looks to host a smorgasbord of metals as Quinton noted in his presentation of the company. What the grades will be in this 180m interval I sure have no idea. It is of course positive that the company seems to have identified several larger breccia pipes and interestingly this Santa Barbara pipe sounds a bit different compared to the breccia pipe that was tested first:
Tom Larsen, Chairman and CEO of Eloro, commented: “The discovery of a new breccia pipe and outlining of a number of potential targets for breccia pipes is highlighting the potential for Iska Iska to host a significant bulk mineable polymetallic deposit. We are currently preparing access roads to enable additional surface drilling to further evaluate the new pipe as well as drill-test other potential breccia pipe targets.”
Dr. Bill Pearson, P.Geo., Chief Technical Advisor for Eloro commented: “The alteration in the Huayra Kasa breccia pipe just east of the underground workings is principally argillic and sericitic which is typical of higher level mineralization in a porphyry-epithermal complex. In contrast, the alteration in the newly discovered Santa Barbara Breccia Pipe is principally silicification. This and the presence of copper, tin and bismuth in the core of the breccia indicates that we are getting closer to the magmatic-hydrothermal source. Furthermore, given the strong association of gold with bismuth in the high-grade zones at Huayra Kasa, gold is likely to be present. It is also very likely that there is a major tin-copper-bismuth porphyry system beneath these breccia pipes; this possibility will be tested in the next round of surface diamond drilling. Meanwhile we are excitedly waiting for more assay results.”
… We know that Iska Iska is probably a hybrid system composed of both porphyry as well as epithermal and we know that epithermal systems tend to be barren or at least pretty low grade in the higher levels. Why I point this out is that it sounds like the mineralization that has been intercepted in the Santa Barbara breccia pipe sounds to have been formed at deeper levels than Huayra Kasa (the first, smaller breccia pipe). This begs the question if there is chance that at least the epithermal mineralization might be better here since it could be closer to the boiling zone level(?). It’s also worth noting that the company believes there might be major tin-copper-bismuth porphyry system beneath all these breccia pipes…
I have no idea what for example the 180m interval of mineralized breccia from the Santa Barbara pipe will show but it sounds like the company has discovered a lot of additional target and that this story might become much more interesting over the coming weeks and months…
