Precious Opals in Canada
October is Opal month and it has been interesting to read about various opal deposits from around the world in the October issues of the popular American published Lapidary Magazines. These articles have discussed various opal sources; however, there was no reference to an opal source in Canada. It would seem that there is little awareness of the Klinker Opal Deposit - Canada's first precious opal discovery being contemplated for commercial production - located near Vernon, B.C. Perhaps in this short dissertation we can start to fill this information gap.
Discovery and Commercial Development
The Klinker Opal Deposit was discovered on October 14, 1991, our Thanksgiving Day, and has been technically reviewed in two articles co-authored by the Geological Survey of Canada and the B.C. Geological Survey. Also, there have been several articles in past issues of both Lapidary Journal and Rock and Gem about this deposit.
Since its discovery in 1991 extensive progress has been made towards commercial development of the property. Likewise, during the past three years there has been considerable activity and some success by others looking for additional precious opal deposits - yes! There is precious opal in British Columbia, Canada!
With determined effort beginning in 1994, Okanagan Opal Inc. has explored and developed the Klinker Property to the stage where adequate reserves of opal have been identified to support small scale mine production provided that an adequate market can be developed. Since 1995, the company has been researched and developed various techniques for product manufacture. Market testing to assess consumer acceptance has been ongoing through its in-house retail outlet located near Vernon, B.C. The company is now preparing to expand its market base through a wholesale marketing distribution plan, the implementation of which, is the final remaining hurdle to commercial production.
An introductory opal product line of a variety of gold and silver jewellery settings has been developed by the company in order to test the marketability of "Okanagan Opal" in its various forms. This effort is increasingly meeting with both success and amazement:
The most common statement made by consumers and wholesale buyers alike is: "This opal doesn't look like the Australian opal that I am familiar with!" Our typical response is: "No, you are right!"
Then we proceed to show these potential customers solid white to honey base colored opal from the Klinker deposit that is very comparable or better than the average white opal found in many jewellery stores. We go on to explain that there are other "types of opal" which are not often seen in the average jewellery store - these other types of opal are generally more expensive.
Opal from the Klinker Deposit (and opal that we have seen from other more recently discovered opal occurrences in B.C.) would be generally classified as "boulder opal". This material exhibits variable base colours ranging from transparent, water clear to clear amber to translucent/opaque white to dark brown and exhibiting a variable intensity "play of colour" in a flash to broad flash pattern. The brightness and pattern of the play of colour in Okanagan Opal is second to none; often covering the full spectrum and covering the full brightness scale.
Yes, there is "solid" opaque to translucent, white base colored opal on the Klinker property; similar in appearance to Australian white opal. The Okanagan Opal found on the Klinker Property has a variable play and intensity "play of colour" and it generally exhibits "flash to broad flash fire patterns" rather than the more typical pinfire pattern found in much of the Australian white opal. In fact, on the Klinker Property there is solid opaque, solid semi-crystal and solid crystal opal; all with broad ranging base colours and broad ranging pattern and intensity of colour play. However, the economic potential of the Klinker deposit is at this stage reliant on the development of the "boulder opal" segment of the market because to date the volume of "solid" opal is not sufficient to justify commercial production on its own.
Perhaps this should be considered a blessing, because when comparing different types of opal, boulder opal is generally more highly valued than opaque white base colored opal. Although the Australians are still producing considerable quantities of white base colored opal it would appear that they are no longer producing the historic quantities of high quality solid black and crystal opal because it is becoming more rare. As an alternative, the Australians appear to be increasingly involved in marketing boulder opal to take up the slack. This should result in the increased awareness and value of boulder opal in the marketplace which as a consequence will result in increased acceptance of precious opal from British Columbia.
Okanagan Opals are cut into 5 types of Gemstones
The manufacturing and cutting techniques used and the product produced by Okanagan Opal Inc. are similar to those found in the "opal industry" worldwide.
