Whiter Clays and Grinding Capacity:

Two problems solved in one place!

This is at the Whitemud Resources meta kaolin (calcined kaolin) site midway between Scout Lake and Wood Mountain, Saskatchewan (their product substitutes part of the cement in concrete to increase strength). They have a giant plant (the dome is big enough to play soccer in) and are capable of processing an order of magnitude more than we can. The mining face in their quarry appears to have the same layers that we mine in Ravenscrag. But, there are very fortunate differences:
-This deposit is near Flintoft, these clays will be much purer and whiter than what we can get in our Ravenscrag quarry (pending testing, of course).
-We need what is above the coal seam, they need what is below (their garbage is our gold).
-The layers appear to be the same as those in our existing quarry.
-Their grinding plant is capable of micron-sizes and is gigantic.
-Their by-product is silica sand!
-They are working on a mining plan for August extraction.
This is close to a "marriage made in heaven", we shall see. It is certainly going in the direction of enabling us to improve product quality. And hopefully, soon make an all-Canadian porcelain.

An update of the book "Clay Resources of Saskatchewan". The cover photo is titled "Kaolinized sand of the Whitemud Formation". The writers are lamenting the underutilization of this resource and almost pleading for industry to recognize its value! The cover shows the mining face at the historic Claybank brick plant. This clay is far whiter than what Painsman Clays mines at Ravenscrag, Sask (about 250km west of this). This site was mined from the 1800s to 1970s. Bricks were made in half a dozen large beehive kilns and, even though reduction-fired with gas, they burned far too white. The company increased reduction to the point that soot formed on the bricks to darken the color and turn them brown!

We are finally listening and rediscovering how much whiter and more pure clays are further east in Saskatchewan (compared to our current mining site in the west). This hill is kaolinized sand, that sand can be removed to produce a Canadian raw kaolin that could replace much the hundreds of thousands of tons that are currently imported each year from Georgia, USA.

El Dorado of Pottery Clay Finally Found!

It has been five years since getting and testing samples of an amazing porcelain-like, clean-burning, highly plastic middle-temperature stoneware raw material from south central Saskatchewan. It is far superior to anything we have now. But, due to mix-ups, it appeared its location had been lost! But coming here to search again has turned up new information and I am quite certain this is the site (at Flintoft, Saskatchewan). Seeing and walking it has confirmed, contrary to the information we had, that the site is highly suitable for extraction (previous mine workings to the left are not shown). And, it is not the only site in the area. The Whitemud clays here are quite different from those in our Ravenscrag quarry. On seeing the range and quality, I am beyond excited! There are a lot of ducks that have to be lined up to be able to actually extract from a site like this, but the location has a lot of advantages. The current economic realities will be a powerful motivator to developing Canadian clay sources.
