RPX

” or the “

Company

”) (TSXV: RPX. OTCQB: RDEXF) is pleased to announce preliminary metallurgical results from 26 of 71 samples at the Wawa Gold Project (the “

Project

”) in Ontario. The samples were subjected to cyanidation bottle roll testing by SGS Canada Inc. at Lakefield (Ontario) (“

SGS

”) as part of the Company’s 2026 metallurgical variability testing program in preparation for a prefeasibility study (

“PFS”

), targeted for completion by mid-2027.

2026 Metallurgical Testing Results Highlights (Figure 1 and Table 1):

Cyanidation test work yielded gold extraction averaging 93.4% at an average calculated head grade of 4.42 grams per tonne gold (“

g/t Au

”) for samples within zones defined as potential initial open pits.

For underground material, gold extraction averaged 88.3% at an average calculated head grade of 8.24 g/t Au for development zones outlined in the 2026 Preliminary Economic Assessment (“

2026 PEA

”) (see news release dated February 18, 2026).

Michael Michaud, President and CEO of

RPX Gold, commented:

“The latest preliminary metallurgical results are very encouraging and provide further support for the development assumptions underlying the Wawa Gold Project. Importantly, the samples representing areas with starter pit potential returned an average gold recovery of 93.4%, compared to 88.0% gold recovery assumed in the 2026 PEA. Samples representing the underground mine plan averaged 88.3%, demonstrating strong recoveries across a range of grades and mineralogical characteristics.

“These results further val
