The Cutting Edge

Monthly Newsletter of the Ottawa Lapsmith and Mineral Club

During the winter of 2016/2017 there was a flood in the basement of 1000 Brookfield which caused $40,000 in damages that insurance didn't cover. Our share was just over a $1000.

There is interest within the executive of changing the club's status from "For profit" to "Non-profit". It is no easy thing. Back in 1997 the club executive at that time made the club a "For profit" Ontario corporation.

The workshop is up and running but Wednesday will be on reduced hours in March because our workshop supervisor Jean-Guy will be travelling.

There is growing interest in a beading course that might happen in the spring some time.

Gems and Minerals in Russia Monday, March 19, 2018, 7:30 p.m. – 9:30 p.m. Location: OLMC Workshop 1000 Brookfield Road, Ottawa, ON

Canadian Museum of Nature Research Associate Gemmologist Willow Wight attended the 30th International Gemmological Conference held at the Russian Academy of Sciences in Moscow, Russia in July, 2007. Accompanied by her husband, Quintin, she joined in the pre-conference and post-conference tours of diamond, emerald, and demantoid garnet mines across Russia from Mirnyy in northern Siberia to Ekaterinburg and Arkhangelsk. Willow and Quintin together will describe aspects of the journey, illustrated with photographs of the mines, their products, and some of the spectacular finds. They will also cover some of the magnificent collection of the Fersman Mineralogical Museum in Moscow, and the Urals State Mining Museum in Ekaterinburg. The nature of the occasion merits some short mention of the local scenery and geology as well"

↑ This fabulous display of uncut diamonds was prepared by the Alrosa Company Limited to celebrate 50 years of diamond mining in Mirnyy,

Yakutia, Russia. There is no glass on the case. The artist is the lady at the back. She's known throughout Russia as “the artist who paints with diamonds”. The red stones are associated garnets, and the green, diopside.

Mines Seleine, a K + S Windsor Salt Ltd. property, is located on Grosse-Île in the Magdalen Islands. It is Québec’s only salt mine.

History

In 1972, the Québec mineral exploration board SOQUEM discovered the salt domes on the Magdalen Islands, including the dome on Grosse-Île. There are seven domes in all. One of the domes, the closest to the surface, is located under Grosse-Île, and rock salt has been mined there since 1982. The salt is used for road de-icing.

How were the domes formed?

The Magdalen Islands are located at the centre of a vast undersea plateau known as the Magdalen Shallows. A surprising fact is that around 360 million years ago, the plateau was actually situated on the Equator. There, it formed a sunlit valley that was periodically flooded with saltwater from the sea. The strong sunlight caused the water to evaporate, leaving a deposit of salt. Over several million years, hundreds of metres of salt crystals formed, and were then compressed and hardened to form rock salt.

As the continents drifted apart, the Magdalen Shallows left the Equator and moved to their current position in the Gulf of St. Lawrence. It is thanks to the buoyancy of the salt domes beneath that the Magdalen Islands emerge from the waters of the St. Lawrence.

Mining to a depth of 489 metres

Although the domes are close to the surface, mining takes place underground, at a maximum depth of 489 metres. Mines Seleine uses a room-and-pillar mining method, explained below.

•Mining takes place on several levels. The mine workers use a ramp to access the various levels of the mine. •Each level is mined in a way that creates empty “rooms” between a series of “pillars” that hold up the roof. •A cutting machine is used to make a clean horizontal cut at floor level. Each cut prepares the wall of the room for blasting, over a width of up to 25 metres. Drillers create horizontal and vertical drill holes to prepare for blasting.

Several galleries allow equipment to be driven through the underground network of rooms. This can be seen in a video of Premier Philippe Couillard, announcing the signing of an agreement between Mines Seleine and the Québec department of transport, sustainable mobility and transport electrification transport to provide de-icing salt to make Québec roads safer in winter. The Québec Mining Association also addresses the same topic in a humorous clip that can be viewed here (French).

The mine produces over 1,300,000 metric tonnes of salt each year.

The 52nd annual gem, mineral and jewellery show for the club will be held at the Nepean Sportsplex, September 15-16, 2018. Unfortunately, the club could not get the next weekend, but maybe next year.

Based on last year's post-show meeting, there are some intriguing ideas to make improvements including advertising and how certain areas of the show could work better.

One of those areas is the position of Show Chair. The club should not rely on the same person year after year to organize this critical activity, until that person suddenly leaves. I hope that one or two other club members could take on this role once or twice in order to provide a reliable backup team in case of an unforseen disaster.

The Show Chair is a single point of contact for the show, can delegate tasks to the team, and makes sure the work stays on track. In my opinion, a person who already has experience managing a small team or who has some project management background will do well. For anyone who wants to learn these skills, it is a great opportunity. I look forward to mentoring anyone who is interested. The Executive Committee appoints the Show Chair after the Annual General Meeting in April.

Also, everyone, please consider volunteering for some sort of task at the show, whether it is helping to advertise, for setup/takedown, or for a two-hour shift at one of the booths. I think they are all enjoyable experiences, and the time passes quickly. Of course, you would still find plenty of time to take in the show and shop.

2018



As of this moment it looks like a go!

We will depart Ottawa Saturday April 21st and return Sunday April 29th.

The game plan is to do 3 days of collecting, mostly by boat, to some of the more obscure localities and two or more days touring museums, private collections, touristy sites, etc. We will have a collecting guide. We have been invited to visit two private collections to date. Costs to participants have yet to be determined.

Tides will be most favorable April 21-26.

This fieldtrip may be scrubbed at the last moment due to a week of bad weather. No rock is worth dying for in the cold cold ocean! Kerry Day, [email protected]

The owners of La Fibule (www.lafibule-inc.com) have offered to visit the workshop and provide a design/fabrication course on a weekend, free of charge if the club can provide accommodation.

Would anyone be interested? Let us know, and we can explore further what would be feasible, OLMC Executive (see our e-mails at page 9) or to any Workshop Supervisor

The club has just received a donation of many items. These are gemmological instruments and the owner who is retiring from the profession wants them to go to someone who can use and truly appreciate them!

There are the following items: Microscope, The Gem Dichroscope, Ohaus -weight scale, Prism Spectroscope, A D Leveridge weight & gauge estimator, Rayner Refractometer, Light source, Fibre Optic-lite Illuminator, Polariscope.

The replacement value for all of the above is estimated at about $3950. The resale value on the used individual items should be about 1/2 of retail. I ask $1800 for the lot, and would not settle for less than $1500. If you are interested in purchasing any or all of these items, please contact me Eileen Moss at [email protected] or go visit this link:
