Like ORD, BNZ is taking an approach to exploration in which they demonstrate where they will drill such that investors can get a sense of what could come from successful drilling.
Below is from today's release on the southern end with the '+' symbols marking pierce points.

Below is from a prior release on drilling at the norther zones.

30km of drilling that is funded gives scope for some serious resource expansion at Glenburg whilst a reasonable EV of $55m means that if the assays come back showing resource expansion is coming, it can re-rate materially.
I like this one as I think there is a reasonable case that some time next year we can be talking about it being 1-2moz with further upside and how large a plant may be. The current EV and ounces also limits the downside. As such, I see this as an attractive asymmetric bet on an explorer, something I have found a lot of lately.
