Bill deLorraine (St. Lawrencs Zinc Co.)  talks on Balmat Zn Deposits of New York State

Geology Seminar, Friday 4/18, 1:30-2:30 PM

After graduation from Watkins Glen High School (soft rock country) Bill moved to Potsdam (hard rock country and good mineral collecting) where he studied Geology at SUNY Potsdam.   Upon graduation in 1974, Bill landed a job as a surface diamond drill  “core logger” in the Geology Dept. at the St. Joe Zinc mines at Balmat, NY after having applied for “any job at all”.  Before long he was underground logging core and mapping development headings in the Fowler orebody of the new  #4 Mine and mill complex at Balmat.   During the course of that year he gathered  map,structural, and geochemical data from the Fowler that ultimately became incorporated into his MSc from UMass at Amherst, 1979.  There he studied under Leo Hall, longtime “Friend of the Grenville”, with emphasis on metamorphic structure, metamorphic petrology and economic geology.  Bill enjoys mineral collecting all over the NW Adirondacks and environs, collaborating with colleagues including Dr. James Carl, Dr. Jeff Chiarenzelli, Severn Brown, trying to decipher the structural geology of the Balmat zinc mines, the ultimate genesis of the zinc deposits, and determining the whereabouts of the proverbial “Mother Lode”.
