Amarc’s technical team completed a comprehensive evaluation of historical data associated with the IKE District, and combined it with  its own more recent exploration data and analyses from the eastern area of the project. The latter includes 189 km² of geological mapping, 3,017 surface geochemical samples, 163.6 line-km of IP, 1,609 line-km of airborne magnetics, and drilling of ~18,000 m of core to 2018. This comprehensive analytical approach rapidly advanced the understanding of the discovery and development potential of the IKE District – especially for higher value intrusion-related replacement and porphyry Cu-Au±Mo-Ag deposits within the Greater Empress Area.

In addition to the Empress Deposit and Granite deposit target, the 35 km² Greater Empress area includes six identified porphyry and replacement-style Cu-Au±Mo±Ag deposit and exploration targets. A table of selected results from historical drilling is provided below followed by summary descriptions of the deposit and exploration targets. 

IKE DISTRICT: GREATER EMPRESS AREA & OTHER TARGETS
Selected Historical Drill Intervals

Notes:

1. Widths reported are drill widths, such that the thicknesses are unknown.
2. All assay intervals represent length-weighted averages.
3. Some figures may not sum exactly due to rounding.
4. (-) means not assayed for.
5. Copper equivalent (CuEQ) calculations use metal prices of: Cu US$4.00/lb, Au US$1,800.00/oz, Ag US$24.00/oz and Mo US$15.00/lb and conceptual recoveries of: Cu 85%, Au 72% ,67% Ag and Mo 82% . 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)+ (Mo% * (Mo recovery / Cu recovery) * (Mo $ per lb / Cu $ per lb)).
6. The estimated metallurgical recoveries are conceptual in nature. There is no guarantee that the metallurgical testing required to determine metal recoveries will be done or, if done, the metallurgical recoveries could be the same as the conceptual recoveries used to determine the CuEQ.

Empress East Cu-Au-Ag Replacement Deposit Target

• Located - ~1.3 km E of the Empress Deposit
• Historical work - limited drilling, with geochemical and geophysical surveys
• Opportunity - good potential exists, with further drilling, to expand and develop previously intercepted good grade Empress-style mineralization. Hole EM24082 drilled in 2024 intersected 33.0 m at 0.67% CuEQ (0.22 g/t Au, 0.53% Cu and 3.4 g/t Ag) from 162 m further supports this potential.

Empress Gap Cu-Cu-Ag Replacement Deposit Target

• Located - in the 1 km gap zone between Empress and Empress East
• Historical work - limited shallow percussion and core drilling, with IP and soil geochemical surveys
• Opportunity - clear potential with drilling to discover additional Empress-style mineralization
• Reference – IKE Report

Buzzer Cu-Au-Ag±Mo Porphyry Deposit Target

• Located – to the ESE of Empress East
• Historical work - drilling intercepted higher grade porphyry Cu-Au-Ag±Mo mineralization
• Opportunity – mineralization may either be part of a small high-level cupola or a large mineralized intrusive-hosted Cu-Au body below as indicated by magnetic surveys: target requires drill testing to depth
• Reference - IKE District Deposit & Other Targets Table, IKE Report

Empress West Cu-Au-Ag Exploration Target

• Located - large target extending >2 km to the W of the Empress Deposit
• Historical work - limited (mainly shallow percussion) drill holes, IP and geochemical surveys
• Opportunity - similar geology to the Empress Deposit with historical works indicating the potential for additional higher grade replacement Cu-Au-Ag Empress-style mineralization, and potentially concealed Cu-Au±Mo-Ag porphyries: modern IP and drilling are required to test a series of defined targets

Other Targets

Several centres of porphyry Cu (e.g. Rowbottom, Mad Major (OMG)) and epithermal Au±Ag (e.g. Battlement, Mewtwo) targets occur in close proximity to the IKE Deposit and Greater Empress area. Encouraging but limited exploration by Amarc and/or historical operators (for example, see IKE District Deposit & Other Targets table) indicate that further survey work followed by drilling is required to establish the potential of these promising targets.
