We are slightly off topic.

But not really.
VRX should just focus on its Silica sand.

We all understand there is enormous heat below the earths surface
which can potentially be tapped.
Geodynamics in Oz. couldn’t make geothermal power work here.
Geology in Oz is different / not suitable
compared to those countries where it does work.

You can look up the history of this in much greater detail if you wish.
But it won’t change anything.
The engineering/pressures/temperatures all made it too costly here.

Article from 7 years ago.
I’ve highlited the reasons it doesn’t work in Australia, compared to where it does work.
………………………………………………………………..
A potential energy source in Australia is set to remain untapped, with a geothermal power project in the far north of South Australia now closed.

Energy company Geodynamics closed and remediated the sites of several test wells and generation plants in the Cooper Basin after deciding they were not financially viable.

Before the closure, the company had managed to extract super-heated water from five kilometres below the earth's surface and use it to generate small amounts of electricity.

"The technology worked but unfortunately the cost of implementing the technology and also the cost of delivering the electricity that was produced to a market was just greater than the revenue stream that we could create," Geodynamics chief executive Chris Murray said.

Professor Martin Hand ran the South Australian Centre for Geothermal Energy Research at the University of Adelaide.
"I think it was talked up too much — it's a very nice concept on the front page of a newspaper, looks very easy to do, and I think it was over-spruiked," he said.
Professor Hand said large areas of the Earth's crust across Australia were very hot and could be ideal for use as a non-conventional energy source.

"Rocks about five kilometres below the surface are at temperatures of around 240 to 250 degrees and, in principle, if water could be circulated through those rocks it could be returned to the surface to produce geothermal power in a power plant," he said.

He pointed out Australian geothermal energy differed greatly from the energy created by abundant and accessible steam vents in countries such as New Zealand and Iceland.

"There are 46 countries around the world that generate significant geothermal energy, but all of those come from conventional systems — where you see the geysers and all the volcanic manifestation, where there is natural permeability in the ground," Professor Hand said.

Geodynamics now talks of a brighter future for bio-gas, the recycling of farm waste and methane for electricity production.

respectfully, rocks ain't rocks.. especially in a country the size of aus. one try in middle of qld does not speak for the whole country's geology.

it's not as silly as it seems and likely some interest down the road...as dept mines seems to think its possible in a number of regions.

strike energy capped at a billion dollars is also doing the numbers.

also too. can the detractors relax, this is just busy work in the back ground at the moment for a "maybe".. drill a bore hole drop in a thermometer and see what comes back... not exactly a pivot.
