Ann: Golden Star Deposit 100% Owned, page-9

Rob...couple of things.

You have been banging on about the negatives of GSN for a while now as is your right if fair & reasonable posts but presume now you have done your DD and summarised your conclusions we won't need to hear from you again?

Also presume you are still waiting for the Qld tenement managers re expenditure requirements on those GSN holdings?

With your latest post, I fail to see where in the announcement that DKM specifies themselves, that the ore is refractory, yet you appear to have come to that conclusion merely at the mention of pyrite?

Rather than be selective eg the picture snip you posted, maybe also post the leach table as per below with the leach summaries. At least you posted your source thanks.

The pic posted is for hole 106 isolated between 83-84m whereas in the table you will see leach results for same hole but at 82-83 & 84-85.

So yeah, while there is a mention of gold within pyrite, it does not automatically define it as refractory ore across the tenement nor that all the ore would need roasting

Best of luck in your trading with stocks that interest you.

We've also learned that pyrite's good for telling us where to pay attention in our search for potential riches. If it's present in veins, we know it's a good idea to look around the area for other, more valuable minerals and metals - yes, even gold. We often associate quartz veins with gold, but there can be more pyrite than quartz in some gold deposits. We now have the ability to analyze it and its inclusions and use it to figure out where to look for various valuable stuff in a mine.

But it's completely true and really quite simple! Picture, if you will, a nice, hot hydrothermal fluid circulating through fractures and pores within carbonate rocks. We're in an area like Nevada's Basin and Range, where the crust is stretched and comparatively thin. Magma takes advantage of zones of weakness, and intrudes into the rocks. Water circulating through the crust gets heated by the magma or by metamorphism. Lots of stuff dissolves in it: gold, silver, copper, sulfur, iron, arsenic, and other minerals. But, unlike the hydrothermal solutions that leave behind rich deposits of vein gold, this fluid is unsaturated. The gold isn't going to precipitate out on its own.

This is where arsenic comes in. Pyrite forms from iron and sulfur, but arsenic can take the place of sulfur in the crystal lattice. It's also able to pick up some gold and carry it along for the ride. We're still researching whether an atom of gold can actually replace an atom of iron - we're talking nanoscale particles, here, so it's really hard to determine that for sure. But we know that infinitesimal particles of gold become part of the pyrite. Some of it is incorporated into the crystalline structure of the arsenopyrite. Some particles just get included with the crystal growing around it, sort of like a nonconformist in a crowd of go-with-the-flow folks. Ultimately, we end up with tiny amounts of gold - maybe 100 parts per million, if you've got a rich deposit. It doesn't seem like much. But the gold contained in these deposits actually makes up some of the richest gold mines in the world. The largest invisible-gold-in-pyrite deposit in North America, located in the Carlin Trend in Nevada, also happens to be the most productive gold mine in the country! It's got more than 107 million ounces of gold in it. And we've got the techniques to get that gold out economically enough to make it worth our while.
