# Three Gold-Copper Zones in One Hole: South Pacific Hits 27 g/t Gold at Ontenu
# US: SPMEF Canada: SPMC
# The setup, in three sentences
South Pacific Metals is a tiny explorer, about a **US$26 million** company, whose flagship ground wraps around two sides of K92 Mining’s Kainantu gold mine in Papua New Guinea. K92 is worth about **US$4 billion**. Same gold belt, same rocks, opposite sides of a property line.
# What just happened, the exciting part
Two things happened in ten days. Start with the drill hole, because that’s the one that gets me excited.
At its Ontenu project, SPMC drilled a single hole, **26-09**, and hit gold in **three separate zones** on the way down. The standout: a slice running **over 27 grams of gold per tonne** (about 28 once you add the copper and silver). For scale, plenty of perfectly profitable gold mines run on just a couple of grams of gold, and K92’s entire mine next door averages about **6.6 grams** (a shade under 9 once you count its silver and copper). One drill slice is not a mine, but a number like that is exactly why people lean in. A *different* one of the three zones spanned more than **12 metres**, and the veins carry **copper and silver** alongside the gold, which nudges the “gold-equivalent” grade a little higher still.
Here’s the part that matters more than any single number. That hole hit the **same vein** an earlier hole, 26-07, had found about **75 metres away**. A monster grade in one hole can be luck; the *same* vein turning up again, along strike, is how you start proving a structure is real and continuous, the line between “nice intercept” and “we might have something.” The CEO’s read mixes excitement and restraint: South Pacific, he says, “may be on the edge of something significant at Megabe,” while noting the story has evolved fast and the team is still learning from every hole. There are at least **eight known veins** along a five-kilometre stretch of this ground, and only three have ever felt a drill bit.
The second piece of news is quieter but bigger in scale: SPMC reopened **Kili Teke**, a separate copper-gold project that ***already*** holds a defined **4.2-million-ounce** gold-equivalent resource, with three of its four target areas barely drilled. So, one project looks like a high-grade discovery catching fire, and the other is a big resource with a lot of untested room.
If some of that flew by, here’s the two-minute grounding on what “proving a structure” means and why sitting next to K92 matters so much. (Already fluent in drill results? **Door #2** has the raw numbers, zone by zone.)
# The life of a mine, and why the crowd shows up late
There’s a famous picture in mining called the **Lassonde Curve**, named after financier Pierre Lassonde. It maps how a mining company’s value tends to travel across its whole life:
[](https://substackcdn.com/image/fetch/$s_!o7pX!,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Ff0b1cd4a-0da3-4528-b147-b46fb88c85c0_600x284.png)
It runs in stages. In **exploration**, the company is just looking: cheap, quiet, mostly ignored, and where most companies live and die. When a drill finally hits, that’s **discovery**: speculation rushes in and the price spikes to its first peak. Then the long, boring middle: **feasibility, permitting, financing, construction**. That’s years of spending money and pouring no gold. The speculators drift off, and the price sags into what the industry calls the **orphan period**. Finally, the mine gets built, pours first gold, and the big institutions arrive, re-rating to a second, bigger peak, until the ore runs out (**reserve depletion**).
The lesson: the biggest gains go to people who are early (before the discovery peak, or in the neglected valley) and turn out to be right. That’s the honest case for the “being ignored is valuable” idea up top.
**The other half, because it usually gets left out:** that tidy curve is drawn for the companies that *make it*. Many more drill their ground, find nothing that pays, and slide quietly off the left edge. Early-stage means the highest potential *and* the highest chance of zero. **South Pacific sits at the far left**. Ontenu is exploration / early discovery: real high-grade hits, but no defined resource yet. That’s the risk and the point, in one.
# How they find a resource, they poke holes
You can’t see a gold vein; it’s buried hundreds of metres down. So, geologists gather surface clues first (high-assay rock chips, soil chemistry, geophysical surveys, careful mapping) to work out *where* a vein probably sits and *which way* it runs. Then they drill. A drill hole pulls up a continuous cylinder of stone, the **drill core**, which is split, logged, and sent to a lab. Picture pushing a thin straw through a layer cake: you only learn about the rock the straw actually touched. One hole is a clue, not an answer.
One hole that hits mineralisation is a **discovery**. To turn a point into a deposit, you **step out**: drill more holes along the way the vein runs (**along strike**) and down the way it tilts (**down dip**), tracing how far and how continuously the gold carries. That’s the “step-out” from the news a moment ago: 26-07 and 26-09 hitting the *same vein* 75 metres apart. Now you can see why that detail matters more than the headline grade. Two points on one line is how “an interesting result” starts becoming “a mapped structure.”
# Why fences don’t matter
Here’s the idea that trips up newcomers most. On a map, SPMC’s ground and K92’s mine are separate properties with a line between them. But **geology doesn’t read maps.** The system that put the gold there formed millions of years ago; the boundary was drawn by people a century ago. A vein can run straight across it, like a **tree’s roots that don’t stop at your fence**, or an underground river crossing three properties that never signed an agreement with it.
Next door, K92 mines the **Kora deposit**: sub-vertical **gold-copper-silver veins**, an 8.6 g/t gold-equivalent reserve, highly continuous over more than a kilometre of strike and depth, and still open. SPMC’s hole 26-09 just hit **gold-copper veins of the same style** on its side of the fence: same belt, same rock, same metals. If those structures run toward, or across, the boundary, SPMC could be drilling the extension of the same plumbing.

**“Could be” is doing real work in that sentence, and I won’t dress it up.** Sitting next to a great mine and hitting the same *style* of rock raises the odds that something meaningful is there. It doesn’t prove it. Grade in a few holes is not a reserve, and as SPMC’s own filings put it, mineralisation on a neighbouring property is not necessarily indicative of what’s on yours. The analogy is a reason to look closely, not a conclusion to bank.
# Why I care, and why you should be careful
This is my largest mining position and I’ve held it for years, which makes me about as biased as a person can be, so run the odds yourself rather than borrowing mine. The short honest version: South Pacific is valued near **US$26 million** while its neighbour is worth 4 billion because K92 **proved** its mine over a decade and South Pacific hasn’t proven anything yet. That’s the whole trade: the biggest upside and the biggest risk are welded together, and you’re being paid to take one for the other.
That’s the short version. Want the actual numbers, every zone, every grade, the copper, the geology, and a real mining primer? I'll post the mining nerd version in the comments
