AuRORA Deposit Discovery Located in the New and Underexplored NWG Target Area
AuRORA Deposit Discovery: Open-Ended, Near Surface, Continuous, High Grade Cu-Au-Ag Mineralization (Section 7800N)
AuRORA Deposit Discovery: Open-Ended, Near Surface, Continuous, High Grade Cu-Au-Ag Mineralization (Section 7900N)AuRORA is an important new high grade porphyry Cu-Au-Ag Deposit discovery made within the expansive Northwest Gossan (NWG) Target an intriguing new area defined through exploration surveys in 2023 that had never been previously drilled.
Our first hole - JP24057 - intersected a new porphyry Cu-Au-Ag system hosting high and continuous gold grades extending from near surface:
- 82 m grading 1.08% CuEQ[1] (1.24 g/t Au, 0.38% Cu and 2.47 g/t Ag) from 18 m depth, including 42 m grading 1.61% CuEQ (1.97 g/t Au, 0.49% Cu and 3.58 g/t Aug) from 58 m depth.
The geological and hydrothermal characteristics of discovery hole JP24057 and other holes along east-west sections 7800N and 7900N announced so far (see January 17, 2025 and January 20, 2025 releases, respectively), are broadly consistent with generalized models for porphyry Cu-Au deposits in the Kemess Mining Camp and in the wider Toodoggone Region. These two sections through the AuRORA Deposit Discovery highlight the excellent continuity of the near surface, high grade Cu-Au-Ag mineralization discovered in hole JP24057, as well as consistent vertical and lateral patterns in the grade, hydrothermal and geological characteristics along both sections. The AuRORA mineralization extends across 600 m on the sections.
[1] CuEQ calculations use metal prices of: Cu US$4.00/lb, Au US$1800/oz., and Ag US$24/oz. and conceptual recoveries of: Cu 85%, Au 72% and 67% Ag.
Another feature of the AuRORA Deposit is the consistency of grade, as shown in the accompanying table of results for hole JP24059 on Section 7800N; for other examples see January 17, 2025 and January 20, 2025 releases.

Notes to Table:
- Widths reported are drill widths, such that true thicknesses are unknown.
- All assay intervals represent length-weighted averages.
- Some figures may not sum exactly due to rounding.
- Copper equivalent (CuEQ) calculations use metal process prices of: Cu US$4.00/lb, Au US$1800/oz., and Ag US$24/oz. and conceptual recoveries of: Cu 85%, Au 72% and 67% Ag. Conversion of metals to an equivalent copper grade based on these metal prices is relative to the copper price per unit mass factored by conceptual recoveries for those metals normalized to the conceptualized copper recovery. The metal equivalencies for each metal are added to the copper grade. The general formula for this is: CuEQ% = Cu% + ((Au g/t * (Au recovery / Cu recovery) * (Au $ per oz./31.1034768 / Cu $ per lb. * 22.04623)) + ((Ag g/t * (Ag recovery / Cu recovery) * (Ag $ per oz./ 31.1034768 / Cu $ per lb. * 22.04623)).
Drill results from holes to the north (8000N, 7900N) and initial holes on three sections to the south (7700N, 7600N, 7500N) of the discovery section were announced in February 2025, extended the known mineralization which remains open.
NWG Target:
- Location: At the northwest end of a possible 15 km mineralized trend that extends southeast toward the GAP and SWT Targets
- Exploration at NWG: 3.7 km2 Induced Polarization (“IP”) anomaly with a 1,500 m x 500 m internal zone of higher IP chargeability, and largely coincident Cu, Au, Mo and Ag soil and rock anomalies plus anomalous elements (Bi±Te±Se±As) indicative of epithermal mineralization overlapping with potential near surface porphyry mineralization. The latter is supported by alteration, and discrete magnetic highs interpreted to represent syn-mineral porphyry intrusions. Porphyry dikes like those associated with Cu-Au mineralization at PINE, Mex and Canyon - are also present in the area. Much of the NWG Target area remains unexplored.
