If 35% of the 258 lbs is gold, that would make the shipment worth ~$1.9M. For 20 days, that makes the yearly rate ~$34M. But presumably the mill is now running better than the first 20 days, and they should be using ore that is 3-6x richer. So $100M yearly revenue is certainly within reason, maybe twice that. A 10x multiple would make $1B, or >$3/share.
