A custom-cut frequency crystal whose refractive qualities are specifically suited to boosting yield when mining Simple Ores such as Plagioclase, Pyroxeres, Scordite, Veldspar and Mordunium. Due to their molecular make-up and the strength of the modulated miner's beam, these crystals will deteriorate through extended use. Can be loaded into modulated mining lasers only. Type A crystals are used with modulated mining equipment and provide steady yields, with low residues and high reliability. A crystal choice for methodical mining operations prioritizing resource utilization over time.
