Kefi and the Lassonde Curve13 Nov 2025 11:27
I had an email from Alberto Alvarez (Substack) who recently wrote a fascinating 17-page report on undervalued silver stocks. In it he covers the Lassonde Curve, especially the behaviour of funded (silver) junior developers, and it’s striking how closely his framework aligns with where KEFI now sits as a junior gold developer.
The best risk–reward point in the entire mining cycle is the funded developer stage – discovery risk has gone, the deposit is economic, but first production hasn’t arrived yet. Alvarez shows that during the “boredom trough” developers often trade at 0.2–0.4 × NPV, then re-rate sharply to 1–3 × NPV once financing is secured and construction begins, especially in a rising metal price environment.
KEFI now ticks every box Alvarez highlights:
Discovery and feasibility risk fully removed (bank-level DFS, defined ore reserves)
Permits in place, government equity committed, and US$240m debt now signed
Equity risk capital oversubscribed and completing in November
Construction already mobilising (roads, power, resettlement, plant contractor on site)
At today’s gold price (~$4,200/oz), the open-pit NPV5% is roughly 10p/share. KEFI trades around 1.5p, which is barely 0.15 × NPV – about half of the 0.3 × NPV level Alvarez cites as the typical “turning point” where developers begin their re-rating phase. Figures still compelling at 10% discount.
Alvarez also notes that in strong metal markets, funded developers can trade at or even above NPV because feasibility-study costs are fixed while gold prices surge, meaning project NPV rises much faster than the market initially prices in. Developers also benefit from having no depletion drag or sustaining capital burden yet (unlike producers), and they frequently become takeover targets as majors scramble to replace dwindling reserves. When sentiment shifts from fear to greed, this stage becomes the highest-beta part of the entire mining sector.
Applying Alvarez’s numbers to KEFI at $4,200 gold:
30% of NPV (normal trough valuation): ~3p
100% of NPV (fair value in a bull market): ~10p
150–200% of NPV (Alvarez premium zone): ~15–20p
So even a move to half of NPV – Alvarez’s conservative benchmark – would still be a multiple of the current price. In strong developer bull cycles the shares often overshoot full NPV because capital pours into funded, leveraged projects as construction milestones are achieved.
If Alvarez’s historical pattern plays out, KEFI is moving from the trough to the steep re-rating leg of the Lassonde Curve at exactly the right time: fully funded, de-risked, and leveraged to a rising gold market. This is the phase where junior developers have historically delivered the largest and fastest returns. If things pan out in line with the above then Kefi delivers multiple returns from the current share price. If it doesn't then Kefi is snapped up for some sort of discount to NPV but still a multiple
