Positive Gold-Antimony PEA Drops Inside A Fast-Track Permitting Regime With Drilling Underway

PPTA approaches EXIM go/no-go vote with $669M cash, a permit-injunction hearing on the calendar, and the stock 24% off all-time highs

Executive Summary

Q1 2026 results (2026-05-11) confirm the project is moving methodically toward final investment decision but two date-specific overhangs sit immediately in front of the stock:
May 21, 2026 — U.S. EXIM Board vote on the proposed ~US$2.7B senior secured loan (~US$2.2B direct loan + capitalized interest/fees).
May 28, 2026 — Court hearing on the preliminary injunction filed May 8, 2026 by environmental plaintiffs seeking to delay certain federal-land construction activities.
Cash position: US$669.5M at March 31, 2026 (down from US$714M at Dec 31, 2025 — burn of ~US$45M in Q1).
Permitting state: Stream Alteration, IPDES (industrial discharge — currently under automatic stay), and Section 401 Water Quality certifications all in hand; second-phase cyanidation permit expected Q2 2026.
EPCM handed off from Ausenco to Hatch for the processing plant — this is the second time EPCM has shifted (Hatch was already named in Dec 2025 for overall project EPCM, so this is a scope re-allocation rather than a fresh appointment).
Zero LTI / zero environmental spills reported in Q1.
The sector roundup item dated 2026-05-19 is unrelated to PPTA's own business; it concerns Rua Gold's Auld Creek PEA (NPV5% US$42M base / US$113M spot, AISC US$1,850/oz).

Material Impact

For PPTA shareholders the Q1 release is Routine - Neutral. It contains no genuinely new information: the EXIM advance to congressional notice was announced March 31, 2026; the permits cited were each disclosed when received; the Hatch EPCM relationship was disclosed Dec 2025. The new datapoints are the cash balance and the May 8 injunction motion.
The injunction motion is a negative incremental disclosure but its impact depends entirely on the May 28 ruling. A preliminary injunction would not kill the project but could delay early works on federal land at a critical construction-readiness window.
The EXIM Board vote on May 21 is the single largest binary event in the company's history. Approval moves Stibnite from "financing-conditional" to "fully funded to mechanical completion" (US$2.2B loan + US$669.5M cash vs. US$2.576B direct capex). A no-vote or material conditions package would force a return to capital markets at much worse terms.
Cash burn of ~US$45M/qtr is meaningful but manageable until financing closes.
The stock at $38.74 is roughly 2.4x the June 2025 low ($16.25) and 24% below the March 2026 high ($50.89) — pricing in a high probability of EXIM approval but giving back some on injunction headline risk.
