One of the links in that list of links is to an article titled:

The evolution of the use of geophysics in the search for blind VHMS deposits in the Abitibi greenstone belt, Québec Canada

Check that one out.

It is pretty decent, and it is even specific to the region that SRSR is focused on, but it isn't specific to gold, rather than specific to "VHMS deposits"... which means "volcanic halide metal sulfide" deposits... so, it could include base metals like zinc deposits, etc.

But, otherwise, what they say about the technology being applied still applies more broadly than only to a specific deposit type.

Metal that is present has electronic properties, and density, that together cause variations in the intensity of gravity... and you can detect and measure the minor variations in gravity that are out there, which allows you to map them, and use them to detect aggregations of metal that are out there, even when they aren't apparent from the surface.

The gravity readings won't tell you "what" is causing the variations... and there are issues with interpretation, particularly as depth is more of an issue...

Metals that are present aren't the only things that alter the gravity readings, either... as even the stresses that accumulate along faults that compress the rocks will show up as gravity gradients...

You can see some linear and circular structures in the map I posted the link to... that are probably directly tied to some of those sorts of physical structures...

You're still left with issues in interpretation, and with resolution issues, etc.

But, when you KNOW you're in an area where there is gold... and you're seeing the distributions on the surface, and have a really good idea about the arrangement of faults, etc., then you can correlate the data you have to figure out where it would be a good idea to look to find "more" concentrated deposits than you've found yet.
