Yes, and that image was one of the trading cards from 1962.

As a source book, I have 'Mining the sky' by John S Lewis. This goes into quite some detail on the composition of asteroids, and how they are mined.

"At the temperatures and pressures prevalent on NEO's the expected source of water [for hydrogen and oxygen] can be either subsurface water ice or water bearing minerals, such as clays or hydrated salts"
... "The equipment needed to extract water from an ice-regolith mixture includes a device for digging, a pressure vessel heated by sunlight .... to distill ... water, and a condenser to liquefy the water for storage. If we desire liquid hydrogen and liquid oxygen propellants, we may replace the condenser with a water vapor electrolysis unit.... supplemented by refrigeration equipment to liquefy hydrogen and oxygen." p103.

he then goes on to say: "The ... [840 second specific impulse] mission requires 83.5 tons of hydrogen. That in turn requires the extraction and electrolysis of 751 tons of water, plus liquefaction of the 83.5 tons of hydrogen made by the electrolysis." p109. etc....

Very detailed, and could be the go. Although I do like the idea of all the skills put by a different poster.
