Ma ka hilinaʻi ʻana i ke kahua ʻoihana hana mīkini nui, ua lawelawe mākou i nā mea kūʻai aku ma ka ʻoihana mining no kahi kokoke i 20 mau makahiki, e hāʻawi ana i nā huahana hoʻolei nui like ʻole no nā umu rotary a me nā wili pōpō.

Loaʻa i ka hale hana nā umu uila hoʻokomo pinepine hoʻololi ikehu 10T a me 15T, a hoʻohana i kahi spectrometer no ka nānā ʻana i nā mea hana aunoa, ka hoʻāʻo ʻana i ka tensile mechanical, a me ka hoʻāʻo ʻana i ka paʻakikī. Hiki i ka hiki ke hoʻolei i 40 tons/ʻāpana, a ʻo ka hana makahiki o nā kila kalapona maʻamau a me nā kila alloy haʻahaʻa he 12,000 tons. Loaʻa iā ia kahi umu ahi kinoea kūlohelohe o 8m × 6.5m × 2.4m. Loaʻa iā ia nā lako hana metala nui e like me 3.5m, 4m, 5m, a me 8m vertical lathes, 2m, 3m, 5m, a me 8m gear hobbing machine, 160 CNC boring a me nā mīkini wili, nā mīkini wili CNC, a me nā mīkini wili. Hāʻawi i nā mea kūʻai aku me ka lawelawe hoʻokahi mai ka hoʻolālā huahana a hiki i ka hana ʻana.
