Fiddle, Kestrel, Black Creek, Anatacau Main, Khaleesi and Hurricane: six programs drilling near historic mines or known deposits, with the geology and the teams behind them. Tap a file for the detail and the sources.
The first hole at the Fiddle prospect, on the Meadow Creek Fault Zone, the structure that controls the Yellow Pine and Hangar Flats deposits, about 750m south of the permitted Yellow Pine pit.
Released Nov 4. Core hole SB633 cut 109.7m @ 3.2 g/t Au, 1.1% Sb from 189.0m, including 2.0m @ 10.5 g/t Au. Follow-up holes were weaker: SB637 returned 37.4m @ 0.7 g/t Au, 0.1% Sb, which Perpetua says extends mineralization about 110m north. Another 21 holes (6,188m) were drilled on strike; results are expected over the coming months. The release gives no true widths. At the Clark Tunnel Fault Zone, partly inside the permitted pit, SB606 cut 25.4m @ 4.5 g/t Au near surface.
The Stibnite–Yellow Pine district sits in Cretaceous Idaho batholith granite and older metasedimentary rocks, with gold, antimony and tungsten concentrated along the Meadow Creek fault zone. USGS work dates the main gold event at 66–61 Ma and the stibnite stage at about 47 Ma. The district was mined from the early 1900s to the 1990s and supplied antimony and tungsten in both world wars. Perpetua targeted Fiddle from historical drilling and underground workings and compares it with the stacked lenses at Hangar Flats (company interpretation).
Stibnite is permitted and in early construction. Reserves were reported at about 4.8 Moz gold and 148 Mlb antimony (2025). The EXIM board approved a US$2.9B loan in May 2026, subject to definitive documents. Any Fiddle resource would need its own review and permits.
First drilling on a magnetic target in ground once read as barren granite or cover, about 20km west of the historic Warrego copper-gold mine.
Released Nov 2. Reconnaissance RC hole WCRC001 cut 27m @ 0.42% Cu, 4.83 g/t Au from 78m, including 2m @ 56.7 g/t Au, 0.88% Cu from 81m; that 2m holds about 87% of the gold. Chalice says coarse gold may be present and is running PhotonAssay checks. All six Kestrel holes hit copper over about 500m of strike, including WCRC010 with 11m @ 0.84% Cu, 0.84 g/t Au. True widths are not known; eight of 16 holes are pending.
The Tennant Creek field has produced more than 5 Moz of gold and about 470 kt of copper from small, steep, ironstone-hosted Au-Cu-Bi bodies in Warramunga Formation sediments, including Warrego, Nobles Nob and Juno (release, citing NTGS). Kestrel is about 65km west-northwest of Tennant Creek. The host is chlorite and hematite-magnetite altered siltstone and sandstone; Chalice says the hematite link could point to a new style (company interpretation). Chalice first drilled Warrego North in 2017 while earning into it from Meteoric Resources; Kestrel is on 100%-owned tenure granted in May 2026.
No resource at Kestrel. A ground gravity survey comes next, then step-out drilling along a 2.2km magnetic trend of which about 500m has been tested. Chalice's main asset is Gonneville, with a 260 Mt reserve and a feasibility study due in H2 2027.
A hard-rock target under a creek that produced placer gold, 6km north of Chicken Mountain in a reduced intrusion-related gold system (RIRGS) district about 40km north of Donlin.
Released Nov 2. CMR26-159, a 100m step-out south of the 2025 discovery hole, cut 91.44m @ 2.86 g/t Au from 22.86m, including 13.72m @ 12.94 g/t Au from 74.68m, which carries about two-thirds of the gold. The hole ended in mineralization at 114.30m. CMR26-157 stopped at 42.67m, above that depth. True widths are not determined; geometry needs oriented core.
Gold was found at Flat in 1908. An estimated 1.4 Moz of placer gold came from streams draining the Chicken Mountain–Black Creek complex, and the Chicken Mountain intrusion appears to have been the main source. At Black Creek, gold sits in hornfelsed Kuskokwim Group sediments with quartz to quartz-carbonate-stibnite veins and intermediate to mafic dykes; Tectonic reads structure as the main control. Black Creek and Upper Otter Creek placers produced about 450,000 oz, and a small Black Creek lode mine worked from 1925 to 1938 (historical, cited in the release). The ground is mostly Doyon land (Doyon is an Alaska Native regional corporation), under a mineral lease; Doyon is one of Tectonic's largest shareholders.
No resource. A maiden Chicken Mountain resource is targeted for Q1 2027 and a PEA for Q2 2027. Assays are pending for about 25,000m in more than 120 holes from 2026, mostly at Chicken Mountain.
A spodumene dyke the company found at surface in 2023, 22km east of and along strike from Rio Tinto's Galaxy project.
Released Nov 4. Assays for AN-26-17, first announced as a visual interval on Oct 15: 302.05m @ 1.73% Li2O from 295.25m, including 142m @ 1.97% Li2O from 426m. Brunswick estimates true thickness at about 80%. The hole is about 100m below AN-26-15 (202m @ 1.31% Li2O) and ended in pegmatite at the rig's depth limit. AN-26-14 and AN-26-16, drilled outside the Anais dyke, are pending.
Anais is an LCT pegmatite of quartz, spodumene, K-feldspar and albite in an east-west deformation corridor. Brunswick's team found the showing in 2023; the largest dyke outcrops over about 15m by 100m. Maiden drilling began in September 2025. The plunge appears to flatten from about 70 to 45 degrees at depth, not yet confirmed. Brunswick earned 90% of Anatacau Main and West under a 2022 option; Electric Elements Mining holds a free-carried 10%. Anatacau West adjoins Rio Tinto's James Bay Lithium project.
No resource at Anatacau. Brunswick's Mirage project holds an inferred 52.2 Mt @ 1.08% Li2O. The CEO says drilling will restart and a larger campaign is being prepared; no metres or timing given.
Skarn on a limestone-batholith contact in the belt that hosts Las Bambas and Constancia, both within 45km.
Released Nov 2. KHZ5790-005 cut 64.9m @ 2.53% Cu, 0.873 g/t Au, 11.59 g/t Ag from 337.6m (3.45% CuEq), including 23.3m @ 4.75% Cu, 1.837 g/t Au from 352.1m. The hole tested magnetite-garnet skarn in an area of limited previous drilling. CuEq uses 2023–25 average prices and an assumed 80% recovery, with no metallurgy yet. True thicknesses are not determined. KHZ5790-006 and -007 are complete with assays pending. C3 calls this the highest-grade copper and gold intersected to date at Khaleesi.
Khaleesi follows a north-northeast contact between Ferrobamba Formation limestone and the Andahuaylas-Yauri batholith, with magnetite, garnet-diopside and pyroxene skarns under thin glacial till. C3 dates the younger mineralization at 35.8 Ma and is still looking for the causative intrusion. In this hole the company ties the high grades to a favourable carbonate horizon at the hinge of a broad fold (preliminary interpretation). C3 said in 2025 that Khaleesi had never been drilled. It is a separate project about 8km west of C3's Jasperoide.
No resource at Khaleesi; about 16,830m in 38 holes drilled to date. Next: step-outs at 50–100m around this hole and a 3D IP survey due to finish in November. Jasperoide's Montaña de Cobre holds 51.9 Mt @ 0.50% Cu, 0.20 g/t Au measured and indicated (2023).
Step-outs along the fault trends south and east of the Hurricane deposit, on a corridor that also hosts the Cameco–Orano Dawn Lake occurrences.
Released Nov 5. Assays from the summer program (26 holes, 10,159m) confirmed earlier radiometric results. Step-out LE26-254 on the East L fault cut 2.0m @ 4.17% U3O8 from 331.5m, including 0.5m @ 15.4%, which holds about 92% of the metal. LE26-250 cut 3.5m @ 3.86% U3O8 50m east of the deposit footprint; LE26-273, inside it, cut 3.0m @ 3.53%. Intervals are not true thickness.
Hurricane is an unconformity-type deposit at about 325m depth, in basal sandstone and graphitic pelite basement, about 40km northwest of the McClean Lake mill. It sits on the Larocque Trend, a regional geological-geophysical corridor. IsoEnergy bought the ground from Cameco in 2018 and hit 8.5m @ 1.26% U3O8 in hole LE18-01A that summer, under VP exploration Steve Blower and CEO Craig Parry. IsoEnergy was set up in 2016 by the NexGen team to hold NexGen exploration assets; NexGen owns about 30%.
Hurricane holds an indicated 63,800 t @ 34.5% U3O8 for 48.6 Mlb, plus 2.7 Mlb inferred at 2.2% (2022). Multi-element results are pending; 2027 drilling is proposed on the eastern projection of the L fault. No resource update timing given.
