Life and work

The son of first-generation Slovak immigrants, Jambor was born in Rouyn-Noranda, Quebec where he spent the first decade of his life. At the age of 10, Jambor and his family moved to Burnaby, British Columbia. He developed an interest in the earth sciences at an early age and after graduating from Burnaby South Secondary School enrolled into the University of British Columbia to study Geology. During summers, Jambor took to traveling British Columbia, Yukon, and the Northwest Territories to expand his studies in geology. A major area of study was Jambor’s research on jarosite, a mineral found in the oxidized zones of sulfide deposits formed in groundwater.

Jambor began his jarosite related research by studying the occurrence of fault zones at the Keno Hill deposit in Yukon. In 1960, Jambor continued his undergraduate studies at UBC where he completed his M.Sc. work with the focus of his thesis research on veneniferous interlava sediments in the Campbell River area of British Columbia. Shortly after the completion of his M.Sc., Jambor joined the Geological Survey of Canada in Ottawa and published three of his first journal articles in The Canadian Mineralogist. In his first journal article, Jambor discussed his first mineral species discovery, gunningite (a zinc sulfate discovered in the Keno Hill region in the Yukon). Jambor went on to discover 34 new minerals over the course of his career. His work in the field of mineralogy and involvement with ''The Canadian Mineralogist'' led him to become the second editor at the helm of this journal.

Jambor was involved in multiple mineralogical projects throughout his time with the Geological Survey of Canada. He assisted with the porphyry copper deposits in British Columbia, the Cobalt-Gawganda arsenide silver arsenide deposits in Ontario, the Strange Lake rare-earth deposits in Quebec, the VMS-type deposits in Newfoundland, the base metal deposits in New Brunswick, and rare-earth deposits in the Northwest Territories.

In 1966, Jambor submitted his eight new sulfosalt discoveries from the Bancroft, Ontario, region to Carleton University for his Ph.D. dissertation. He later became de facto as exclusive member of the “Sulfosalt Club” which consisted of only a few world specialists in the field of mineralogy and the study of some of the most complex atomic systems in nature.

In 1975, Jambor’s began working with CANMET (Canada Centre for Mineral and Energy Technology), where he transitioned to working in the field of mine waste mineralogy. He spent the remainder of his career at CANMET where he carried on studying new mineral species until he retired in 1993. Upon retirement from CANMET, Jambor moved back to the Greater Vancouver area and continued his work in applied mineralogy as the head of Leslie Research and Consulting. His work then focused on the mobilization of toxic elements in groundwater supply and studying its consequences at engineering project sites. During this time Jambor was an associate professor at the University of Waterloo and the University of British Columbia. In addition to his contributions to the Canadian Mineralogist, Jambor also worked with the '' American Mineralogist'' on a volunteer basis where he was the New Minerals editor and helped in editing the description of all new mineral species worldwide.

John Leslie Jambor is known for his work in the field of earth sciences, particularly in the focused field of sulfate minerals.

Jambor died on January 18, 2008, after a ten-month battle with cancer.
