Komis Deposit

Using some key words to search for information has led me to draw a comparison between Komis, and another well known historic mine in Canada.

First you have to look up what Rhyolite is:

"Rhyolite is a felsic extrusive rock. Due to the high silica content, rhyolite lava is very viscous. It flows slowly, like tooth paste squeezed out of a tube, and tends to pile up and form lava domes. "

If you look at the aerial photo of the Komis deposit, a lava dome could have been in the location of what is now Round Lake. The drill pattern is unusual and unexpected, through clearly visible. This drill programme went entirely unnanounced:

Also I wondered whether this was not also refractory ore, and stumbled across the following report:

Models and Exploration Methods for Major Gold Deposit Types

This report will certainly challenge your reading skills.

Figure 6 from page 701 in the report has been loaded into the photo gallery. I would caution anyone against assuming that the Komis deposit is uniquely a vein type system.

The lava dome high sulfidation schematic and the drill pattern over the Komis deposit are a match, if you consider that the lava dome is missing. The size of a lava dome in the schematic is about the same size as Round Lake.

You would have to go through the Komis technical report now, and you will notice a series of photos. They are very important to the discussion, since they show you the type of veins in evidence. Obviously not a vein-type system as you would find in Roy Lloyd. Pg 25 - 28:

Now there is one famous mine in Ontario called the Dome Mine, discovered in 1908, which I believe there may still be some production. I would draw your attention to the photos of veins in the discussion of the Dome mine and compare them directly to those found in the Komis mine. Pg. 26 - 29:

Geology Ontario Report

There is an express similarity between the veins in Komis and the veins shown in historical photos of the Dome mine. The Dome mine historical photos, while lacking the contrast of photos from the Komis mine demostrate the similarity of the veins. They compare directly.

What I find aberrant is that Komis, even though it was discovered in the 1950's has only seen sporadic production, though it is very clear that the comparable is the Dome Mine. Nobody has managed to raise sufficient capital to implement a mine over the decades.

Here you can see three drills at a location which has seen drills on site for over two years. They are obviously testing the basement rock, since the drill locations haven't changed in some time. There are several locations over Golden Band property where basement rocks have been or are being tested. For example, Jolu east, Roy Lloyd north, Star Lake and Komis. If you go by the schematic for a lava dome, they would be looking for porphyry intrusions.

The size of the resource

Overburden has obviously been scraped off for 150m on the north east corner of Round Lake. You can assume that the width of the resource is 10m, if you take a hint from the technical report. You can also assume that a cubic metre of rock is 1 tonne. So you have been left with a little math problem, but also have to parse between the lines.

"The updated mine plan for Komis includes two phases. The first, a smaller pit designed to extract the near-surface ore, has total mineable tonnes of approximately 1.7 million. Ore production is expected over nine months at an average of 15,000 tonnes/month at a grade of 6.46 g/t gold. Phase 2 is a larger pit designed to extract ore from the deeper levels of the Komis deposit, with total mineable tonnes of approximately 4.4 million. Ore production is expected over 18 months at a monthly average of 13,000 tonnes at a grade of 7.13 g/t gold."

What they are referring to is specific to the small section at the north east corner of Round Lake, but there's way more tonnage here than a restrictive corner slated for production. If you work through you will find perhaps they are referring to a deposit that is 150m in length, 10m in width, and 325m of depth for production. But over the whole deposit, 325m of depth accounting for all of the tonnage would be over 1km. if you add all of the tonnage, which corresponds to the aerial photo, you get a deposit of 1.7m. ounces.

But this is only the first 325m. in depth. The Dome mine had veins running 2500m in depth, and we've found an express similarity between Dome and Komis. So if the Komis deposit ran the same depth, then you have a deposit that you could infer to contain ~10m. ounces.

Obviously they don't mean to operate by processing just 500tpd. But they can, since the mill has the capacity. My guess has been that the company raised the necessary capital for a new mill by escrowing production over four years, and has embarked on expansion since the presumed 'shut down.' They would be drawing from volumnious stockpiles at practically 10% cost since that time, and escrowing all production.
