What are the properties of red granite and sandstone?  How well do they conduct electrical or magnetic energy?

Those are not the usual questions about red granite and sandstone. Are you asking about the DC properties, or the RF properties? Do you need volume resistivity numbers?

Pure sandstone is silicon dioxide, and is an excellent insulator, and reacts diamagnetically to a permanent magnetic field. It also has low RF losses, and would transmit RF very well. Of course, sandstone is never pure in nature. It is usually mixed with other minerals such as iron oxide, and has a lot of water content, and commonly salt. So the volume resistivity drops due to the impurities, especially water and salt.

Red granite I'm not too sure. It is almost certainly diamagnetic. The bulk resitivity would be lower than sandstone, but what it is I don't know. I could find out, if you can ask a specific question. The RF losses would be higher than sandstone, but once again, I don't know the specifics for granite.

Are you into pyramids Donnah? Red granite like from Cairo and it's said to be alike Mars rock. Cairo means "Mars". The Pyramids are made of a red mineral and were coated on gold. Making it electrified thus preserving the mummies inside. An explorer discovered a charge in a pyramid.

Moses who learned from the Egyptians made an ark of ****tim wood. And coated it in gold. Thus this too was electrically active preserving it's content. Stones but moreso a wooden staff and manna from the desert. ****tim wood has this electricaly effected quality too.

looks like a very rude form of wood they used?

In the interests of scientific accuracy:
1. No geologist or planetologist would claim that red granite was like Mars rock. It isn't.
2. The pyramids are not made of a red mineral. The pyramids at Giza are made primarily of limestone, while the great pyramid has the Grand Gallery lined with Aswan granite.
3. The pyramids were not coated with gold.
4. No mummies were ever found inside the Giza pyramids.

Companies prospecting for oil or minerals use a variety of techniques for detecting ores of interest.

Some rocks have an impact at a distance, like "Magnetic Island" in Australia, which deflected the compasses of early explorers.

But most ore bodies are much more subtle, and often buried out of sight. So prospectors use multispectral aerial/satellite imagery and sensitive devices to measure local variations in gravity, magnetic field, electrical conductivity and earthquake wave propagation (natural and artificial earthquakes) in order to detect the boundaries of mineral deposits.

When drilling for oil, instruments to measure these parameters are often lowered into the borehole to obtain progressive measurements as the drilling proceeds.

The type of measurements and processing of the results is considered a critical trade secret by the prospecting companies, so it's not something they tend to publish. But you could get measurements on bulk rock samples.
