when they last updated Boda the prices they used for calculating AuEq grades were much lower than what the prices are now - $1930usd per ounce and $8600usd per tone.
Current prices are at ~$2330 for gold and ~$10k for copper. Let's assume they use $2k for gold and $9.5k for copper as ALK will probably go for conservative numbers. That will still show decent returns. And anyone can test what the metrics will look like at higher prices.

if prices hold at these levels or move higher over the next 10-12 weeks then SS will be showing very attractive metrics.
