Oh, Gosh, I leftout Quote Marks around Hugh J Abercrombie, Ph. D. Birch Mountain Model study with Nevada/ Great Basin USA comparison that I paper Refered to in last post : at Birch Mountain Presentation:( If one suceeds...all NEWTECH MINERS SUCCEED: ) So Says...Dr Hugh Abercrombie at the BM Meeting:( This is the best Info)So Far! <<..." Let me begin with a rhetorical question... What if there exisited a type of gold-PGM (plattnum group metals) deposit that did for PGM's what Nevada has done for gold? Currently, Nevada produces more gold than Canada. I would like to explore the possibility that Prairie-type deposits under exploration on our Athabasca property in northeastern Alberta represent a previously unknown type of sediment-hosted deposit closely related to non-igneous associated, unconformity related, sediment-hosted gold deposits In Nevada. Over the past year, we have come to recognize that the Prairie Gold model developed by Birch Mountain is indeed a low temperature variant of this important class of sediment-hosted precious metal deposits. This recognition has primarily been driven by our detailed examination of cores obtained from oil sands operator Syncrude and structural mapping using core-based Information combined with results of our 1997 high resolution aeromag survey. Preltminaiy geochemical indications of alteration which we recognized over a year ago have now been extended such that we can recognize characteiistlc alteration types including decarbonation, desulfidation, sideritlzation, haritization and, locally, silicificatlon In areas of structural disturbance directly overlying basement faults. We can now show that the "ore grade" platinum and gold from Syncrude drill hole AE/l1-7-96-10W4 (2.2-5 g/T platmuxn and 0.2 g/T gold over a 1.6 m interval from 72.0-73.6 in depth) occurs within cbaractexistically altered Devonian limestone within 1 kilometre of a basement structure which coincides with an alteration fairway" at the top of the Devonian. I would like to draw your attention to the attached paper. "Application of mineral deposits models in exploration: a case study of sediment-hosted gold deposits, Great Basin, western United States" by Sam Adams and Borden Putnam. This paper is amazing to read when you keep In mind what we have been attempting to do In applying the Prairie Gold model in Athabasca and Manitoba. Recognition by Adams and Putnam of the role of deep crustal structures and unconformities as pathways for ore-forming solutions parallels directly what we see in Athabasca. Furthermore, they show that a number of unconformity-related, sediment-hosted gold deposits In Nevada are not associated with any known volcanic or plutonic heat sources. Birch Mountain continues to use the Prairie Gold model as a guide to Its exploration for large-tonnage sediment-hosted gold-PGM deposits. We currently are in the process of 1dentifying drill targets to test sediment-hosted platinum and gold targets in Athabasca. Plans for drilling are expected to be announced once financing activities currently underway have been successfully completed."...>> From Huge Abercrombie above. Chucka-I am impressed. Global has impressed me, can't catchup!( I say Arizona also, in places.)We don't want the real full cirlce, Richie - we want the PGM Model Kind of fluid spirils. Understood in 1999 and in production 2000! Onward 2,000. PS- RE..<<..including decarbonation..>> Text Book Definations are interesting, lookkup in case I can't find in my Sedimentology Text Book: Page 281- Secondary Porosity and sandstone diagenesis. DECARBONATISATION- ...effectively during deep-buried diagenesis following dissolution of the CARBONATE - CEMENTING minerals calcite( a Low TEMP thing Chucka adds from talking to Hugh), dolomite, and siderite ( see my LIMESTONES NEWTECH UNDERSTANDING of this 1999 year?) results from decarboxylation reactions involving organic material , the CO2 so produced combining with the formation waters to form acidic solutions.... P.S.- Why is right...have no clue. Not shorts...as it is too good a reason...confounditall. Dumb shorts( but/yet-just MAYb...not smart shorts, I should say!) Daffy Action on a pre whatever upcomming!
