ODH057: Tops of alkalic Au-Cu porphyry systems: Exploration challenge & opportunity - Alan Wilson 

Thanks Alan for an informative talk!

Thanks. Perfect presentation

Thanks for this very informative virtual talk....

The talk begins with mention of Lihir and Emperor, and surely these are examples of the top, "lithocap" of alkaline porphyry systems. At Lihir a sericite pyrite Illite cap lies above an intense potassic altered, anhydrite veined, monzonite core, with elevated Cu Mo (not economic). No albite present. The illite Phyllic cap get more illite rich as you approach the surface, (it holds much of the gold), where it is capped by intense kaolin rich blanket, in turn capped by Alunite rich/ slice bleached rocks forming around and below the active hot springs (h2S rich). It is described as a low sulphidation deposit. Yet there is no shortage of sulphur. The Sericite zone has >5% pyrite. The potassic zone is about 20% anhydrite. The top Alunite zone has alunite and pyrite. the Alunite zone is up to 50m thick. but is being actively eroded. (no gone to mining). Emperor is a bit different, asked by infill sediments.

Thanks

Hello....I am near Randle WA ...I found a large copper deposit and need help. 2 miles long, gold,silver, Hemetite ...Other minerals are in the area. I have known about this for 3 years and have not claimed anything because other people will just start pouring in in my opinion and staking. So I can only contact someone who aquires and keeps it for open pit. The top is flat. I don't know how much overburden because more good minerals might still be up higher. Drill 4 corners. I have a video of the dark, blue green boulders in the wall exposed by slide. 150' tall copper wall 2 miles long, and most likely very wide considering 150' is visible....the end of the wall....has to go in far...high content. Break a piece,wet it and dark blue water comes right out..I will get it tested..tell me where...I need your e mail to send the video Regards, Michael Rowley

Too bad B.C. would rather shake down mining companies using First Nations than actually explore for metals....

Oh you got a masters degree? You think you're my master now?
