BIOGEOCHEMISTRY Discovery Using Metal Concentrations in

Plants — Bisbee (Cochise County, AZ) NUMBER 121 NOVEMBER 2003

Introduction A structurally complex area, approximately 20 miles south of the Bisbee porphyry copper mine, was identified in the late 1980’s for its gold potential. Exposed Cretaceous siliciclastics were mapped to the margins of Quaternary pediment gravels, which obscured what appeared to be the most structurally favorable areas. Because Mesquite and Acacia were widely distributed over the pediment, biogeochemistry was chosen for targeting the drilling program. Mesquite had been used in many earlier surveys with published results, and it was expected that if mineralization were present, Mesquite tissue would be enriched. However, there was no previous experience with White Thorn Acacia, which is the Acacia species with the widest distribution in this particular area. Ground water was known to be 500 feet from the surface, yet the mineralization was presumed to be just 100-200 feet deep. This posed a serious problem for the biogeochemical Figure 1. Geology in the area of the Bisbee biogeochemical survey because experience predicted that without ground survey (1991).

AEG Presidential Address

○○○○○○○○○○○○○○○○○○○○○○○○○

My year as President, has gone quickly. The Dublin IGES provided a pleasant and welcome interlude (and I thank the AEG, Steve Amor once again, for enabling me to attend). It was good to meet with so many of you in Dublin and I would like to congratulate the local organizing committee on their achievement in organizing a successful and profitable event, in the face of continuing uncertain times for the mining and exploration industry, in the world in general and Ireland in particular. The LOC of the 2005 Symposium in Perth, well represented in Dublin, are hitting their stride and I am confident that the “IGES momentum” that Dublin maintained so successfully will endure for a good few years yet! The AGM held on Monday September 1st was marked by an update regarding progress in changing the By Laws, which led to the passing of a motion that the AEG President’s term of office be extended from one to two years. There will be further discussion by Council regarding when this takes effect and how it is phrased in the ByLaws. The majority of the meeting was, however, taken up with discussion about the change of our Association’s name. I had been hoping that in this last Presidential Piece appearing under my photograph, I would be able to put a seal on our association’s name change. At time of writing, it appears that this will not be possible. Although a majority Paid Advertisement Continued on Page 3

IN MEMORY A Truly Remarkable Man

The world has lost a great geologist and geochemist, and a great Canadian who had contributed to his country for over 60 years. On Monday, August 5th, 2003, Robert William Boyle left this world peacefully after a long struggle with illness, and a much longer struggle with failing eyesight. The latter had not curbed his determination to finish his most recent scientific endeavour, his ‘History of Cosmochemistry and Geochemistry’, which is being considered for publication by the McGill-Queen’s University Press. He completed the last editorial work on the Preface the day before his death with assistance from his daughter- in-law Christy Vodden. Bob, born June 3rd 1920, grew up near Wallaceburg in southwestern Ontario. It was there that he developed his interest and love for the natural world. As a teenager he learned to trap, and saved his earnings from muskrat and mink pelts for his future education. Even from those early days Bob was intrigued with chemistry, and had his own laboratory in the attic of the family farm. It was his friendship with James McCrae, a 70-year-old retired prospector, living two farms away that was critical. One can imagine the impression that the stories of prospecting in Northern Ontario had on the teenager who loved the outdoors. During his last two summers at Wallaceburg High School he decided Robert W. Boyle to earn the money that would enable him go to university rd and study geology. With contacts from McCrae he joined a Just eight days later on November 3 Bob married his prospecting syndicate in northern Ontario, where he started childhood sweetheart, Marguerite Brown, who had at the bottom — cutting line, and as a driller’s helper. grown up on a neighbouring Wallaceburg farm. On Europe went to war in September 1939, and Bob enlisted his honeymoon, it is told, he spent time studying physics in the Royal Canadian Artillery two days before Canada for his university admissions test. In January 1946, joined the war. He used to tell the story of how two Military Bob enrolled in Geology at the University of Toronto Policemen arrived at the farm later to collect the ‘errant son’ as part of an accelerated program available for for not reporting for conscription.

Notwithstanding his military service, Bob still Henderson and I.C. Brown in their Yellowknife, NWT, made time for geology. While stationed in England, he took mapping project. In the Fall Bob immediately geology courses at Imperial College, and correspondence commenced graduate work at Toronto on the courses from Queen’s University, Kingston.

Drill Results Biogeochemical results were used to target the drilling phase of this project. Ten core holes were drilled: five on Line 188, one about 100 feet northwest of Line 188, one on Line 182, and two on Line 162. A few holes were added to satisfy the whims and biases of the geologist, however all of these were barren. Holes 1-4 encountered “anomalous” Au concentrations on Line 188 in a zone of several high angle faults, and one low angle fault. Hole 5 was outside the zone and was barren. Holes on other lines encountered very minor mineralization. Figures 2 through 5 show the relationship of trace metal concentrations in Acacia to the drill results. Relatively high gold concentrations of 0.4 to 0.8 ppb on Line 188 are replaced by relatively high Ag concentrations of 40 ppb on Line 182. Arsenic concentrations halo the Au and Ag occurrences on both lines. Figure 3. Silver and Au concentrations in twigs (2nd year growth) of White Thorn Acacia on Lines 188 and 182.

Section A-A’ shows drilling attitude, depth, structures, relative pediment thickness, and “anomalous” Au mineralization on Line 188. Conclusions Porphyry copper systems have recently been the targets for satellite precious metal deposits. The Bisbee Project was an early assault on this theme. Biogeochemistry was an easy choice for targeting the later drilling phase because of the wide distribution of Mesquite and Acacia in the area. However, White Thorn Acacia had never been used before, yet other common desert shrubs like Creosote, Paloverde, Sagebrush, and others had been used with exceptional success. Because ground water was not likely to be in contact with mineralization (to the drilling depth of 500 feet), subdued concentration profiles were anticipated during the interpretive phase and factored into the distinction between “anomalous” and “background” (based primarily on experience from biogeochemical results at the Pinson Mine, Nevada). Drilling results confirmed the biogeochemical anomalies and additionally found no mineralization in areas

The GEEA Journal covers all aspects of the application of geochemistry to the exploration and study of mineral resources, and related fields, including the geochemistry of the environment. Topics include: the description and evaluation of new and improved methods of geochemical exploration; sampling and analytical techniques and methods of interpretation; geochemical distributions in and around mineralized environments; and processes of geochemical dispersion in rocks, soils, vegetation, water and the atmosphere. Papers that seek to integrate geological, geochemical and geophysical methods of exploration are particularly welcome. Given the many links between exploration and environmental geochemistry, the journal encourages the exchange of concepts and data; in particular, to develop mineral resources while protecting the environment. GEEA is published in partnership with the Geological Society of London (http://www.geolsoc.org.uk/). ASSOCIATION OF EXPLORATION GEOCHEMISTS PAGE 24 NUMBER 121 EXPLORE
