Pinned straw:
Additional: I forgot to mention MinRes' Mt Marion lithium mine where Develop Global have previously been the mining contractor for the underground development at Mt Marion, having won an 18-month, A$46 million contract in late 2023 to establish an exploration decline, with operations managed by joint venture owner Mineral Resources Limited (MinRes). MinRes managed all mining activities at Mt Marion, but Develop was handling the specific underground setup for future resource definition. That fixed price ($46m) Mine Development Contract was awarded by MIN to DVP in December 2023, for an early 2024 start, with an 18-month term, so it's well and truly completed now.
It also looks like while the open-pit operations are ongoing, the underground exploration development at Mt Marion was placed into care and maintenance in December 2024 in response to market conditions, so that DVP contract may have finished then, i.e. one year ago. There is certainly nothing that I have come across that suggests that DVP still have any ongoing work at Mt Marion or any other MinRes mine.
Point being that while DVP certainly do have significant underground mining and development experience and are well regarded in the industry, they only have two ongoing mining contracts, being the Bellevue gold mine owned by Bellevue Gold (BGL) and their own Woodlawn mine. They also have had some shorter term mine development contracts such at Beta Hunt, Mt Marion and now, as announced yesterday, another one over in NZ for OG (OceanaGold). While these development project wins are material, they are fixed term and have not as yet led to any further ongoing mining services work with the same clients. The Bellevue contract is much more material in that it is for ongoing mining, and while also a fixed term contract, it's a multi-year contract that can be rolled over again and again as long as both parties are happy with the arrangement, but the point I'm making is that Bellevue remains their only external mining services contract for actual mining as well as mine development rather than just shorter-term mine development contracts (like the one they announced yesterday), and that side of the business doesn't really rate a mention on DVP's own website beyond their "We get our hands dirty to produce clean metals" (source) which could equally apply to DVP's own mines such as Woodlawn and their most advanced development project Sulphur Springs.
If my memory serves, that slogan used to be "We get our hands dirty so you don't have to", which was much more aimed at potential clients of their mining services arm, but that memory of mine might not be completely accurate. Regardless, DVP is today positioned as a mine owner and operator who also do some limited mining services for other companies. And as I said in my straw last night, there's nothing wrong with that, it worked very well for MinRes (MIN), however MIN's earlier business model was that they were a mining services company that also dabbled in a bit of mine ownership, and Chris Ellison managed to position his CSI (MinRes' Crushing Services International) division as the leading crushing and hauling contractor for the major iron ore players in Australia - they had BHP, RIO and FMG as clients until FMG transitioned to an owner-operator model after the death of an electrician at one of MinRes' crushing plants highlighted MIN's coyboy approach to safety at that time. MIN's CSI still count BHP & RIO as key clients and they have plenty more, but the point is that MinRes had that strong backbone of mining services as their base business which allowed CE to dabble in his own iron ore mines, a little Manganese which didn't go far, then Lithium which MinRes did very well out of, always getting the better end of the deal with global majors like Albemarle and Jiangxi Ganfeng, but especially Albemarle when deals were made or splits were re-cut/adjusted in exchange for cash and/or other assets.
DVP has a similar business model but they're much, much earlier in the journey, just getting started really, and DVP have the mix tilted much more to having a larger mining business and a smaller mining services business, so a different mix to what MinRes were so successful with.
And that's why I believe that to assess DVP's value at this point in time, you really need to look at what metals they are producing at Woodlawn, and are likely to be producing when Sulphur Springs comes online, and it's going to predominantly be zinc at both Woodlawn and Sulphur Springs. And copper and some lead, silver and a little gold, but more zinc than anything else. So my own opinion is that DVP's near-term future upside will be impacted in no small part by what the zinc price does. Longer term it will be driven much more by the many brilliant deals that Bill Beament will no doubt do, just as he did back at NST, but for the next couple of years I'm thinking of DVP as a zinc miner who also produce copper and have a smaller mining services arm.
And that's not attractive to me right now, so I don't hold DVP. But they remain on my watchlist. For anyone who is bullish on zinc (I'm not), DVP could be an interesting play here.
Here's what DVP's Woodlawn Zinc-Copper Mine in NSW looks like (or did 6 months ago):
