Everyone seems a little quite about the House reports. I take it nobody understands them? ha. Well, here's a few random thoughts I have on them since the Chief has not given a overview yet. LIPANGUE 1) Not clear from the report if the surface expression of the pipe is 400 X 150 or 800 X 150 meters in size-probably the later. 2) Results from IP lines A,B,C and D are missing-not sure why-maybe because Geodatos is still working on it-this gives only half the picture or half of a pyramid view of the deposit. 3) Results seem consistant with an annular shell of minerlization surrounding the pipe which is what is typical of a porphyry deposit. Resistivity readings indicate silicification (Quartz with copper sulfides and gold we hope.) is probably what the anolomilies indicate. 4) More overburden over the minerlization as you move away from the center of the pipe 5) Depth of minerlization is at least 250 meters-the limit of the survey. Deeper results could be obtained if they used more current and spaced the electodes further apart.(In this case, they were spaced 100 meters apart.) 6) Andesites are on the West side/Granodiorites are on the East side of the pipe-the pipe developed on the contact of the two formations.(Los Das Marias is West of Lipangue despite what the previous House report indicated.) 7)Don't know the significance of IP anomaly was 4 to 10 times background in PFE-maybe the Chief knows. 8)Pant leg anomaly probably refers to the shape of the IP return-think of a pair of pants upright extending into the ground-this represents minerlization at the top then splits into two with depth-except that you need to think 3-d-the pant legs become an annular shell of minerlization in 3-d. Minerlization typically occurrs around the contact of the intusive body coming up from below 9) No mention of carbonates even though we have been told that carbonates exist. But more on that later. 10)Asarco says the amount of crystalline quartz shows that it was an intense hydrothermal event-higher tempertures/pressures -more gold. LAS DOS MARIAS 1) 6 lines of IP were done. However, House mentions a line 7 and 8. Sounds like we are talking incomplete results again. Lines 1 through 4 are mysteriously not mentioned either. 2) It appears to be no casual relationship between Lipangue and LDM. If there is a relationship, it is more complex and undetermined thus far. 3) Fact: Granodiorite intrusive plutons are the causation for most of the significant gold mantos deposits. 4) Looks like a small intrusive came up close to the surface in the middle of the valley. Hydrothermal fluids generated from the intrusisve entered the limestone and turned it into mantos(skarn-or replacement) deposits. Also the hydrothermal fluids went up the West side of the valley into a shear zone(rocks all cracked up for some reason) and deposited pyrite-arsenopyite mineralization(probably gold and copper as well.) 5)Las Dos Marias seems very interesting-not all the facts are there yet-seems to have more potential than I orginally thought. 6) There is a layer of sillicified pyritic tuffs, sandstone and shaley tuff contained lenses of limestone(carbonate rock) which underlies the Andesites. This layer may extend to Lipangue undernealth the Andesites resulting in potentially a significant replacement deposit adjacent to the much more hydrothermally active breccia pipe and its associated porphyry deposit. Recall that MDIN has stated that carbonate outcrops on the edge of the lipangue plateau. I expect its presence undernealth the missing lines of IP that MDIN left out of the preliminary report. Speculation? Maybe. But an interesting possibility. Overall, looks like we got ourselves a winner. Hang in there. Better times await are around the corner! Note: House assayed all the various rock outcroppings. Results not back yet.
