I liked the complexity of managing randomly produced ores by Versepelles Deep Quarry.
So here's a complete rewrite using recipe probability from 0.15.

Features:

Automatically adds any ore not requiring fluids to a special recipe for deep mines.
Deep mines are available after researching advanced material processing 2.
Performance cost is the same as any base assembling machine + beacon.
Deep mines benefit from mining productivity research.

Basic deep mining produces roughly 1/4 the amount per ore of a mining drill before repeatable productivity.
Advanced Deep mining produces less additional ores and yields around 1/2 the ore compared to a mining drill.
