There are lots of materials that can mined from an asteroid or spent comet and can bring to Earth. These include gold, iridium, silver, osmium, palladium, platinum, rhenium, rhodium, ruthenium, tungsten, iron, cobalt, manganese, molybdenum, nickel, aluminum, and titanium. It is the most important part of Astro mining is the cost of it. As you can expect, it is quite expensive. But with SpaceX and Black Falcon, costs for such a thing dropped a lot and because of companies need to go deeper for new mines on the world, current mining costs are rising every day. In near future (2024 expected) Astro mining can be cheaper than current mining operations and companies can choose to move their operations into space.
The name of the ico is also Astro Mining. The current news about the development is: "Over the past few weeks, AstroMining has been collaborating with a local space station on unveiling the science behind Asteroid Mining, but most of all, how to bring an asteroid into earth orbit so we can mine them" They will use the funds from the ico for research, development, prototype and etc.
In conclusion, there are not very much details about the project but the topic is already interesting. It is not a project you can expect a return in 3 months but it is something which you can make proud years later because you choose to be a part of it.
