JZR GOLD REPORTS UP TO 130 G/T GOLD IN CONCENTRATE, CONFIRMS PROOF OF CONCEPT AT VILA NOVA PROJECT, BRAZIL

JZR Gold Inc. has released sampling results from initial gold concentrate produced at its Vila Nova gold project located in Amapa state, Brazil.

Initial concentrate samples, collected from the company's bulk sampling mill operated by its joint venture partner Eco Mining Oil & Gaz Drilling Exploration, returned assay results of up to 130 grams per tonne gold. The samples were prepared and submitted to SGS Laboratories in Belo Horizonte, Brazil.

These results mark a significant milestone for the Vila Nova project. The processing circuit has demonstrated the ability to produce a high-grade gold concentrate, confirming that gold can be effectively recovered from tailings material at site. The process works, and the assay results from SGS demonstrate the value of what the mill can produce when operating as designed.

"These results validate what we believed the project could deliver," said Robert Klenk, chief executive officer of JZR Gold. "The mill is producing a high-grade gold concentrate, and SGS has confirmed it. That gives us a clear proof of concept. Our priority now is to improve consistency and reliability as we advance toward initial concentrate sales following the rainy season in May."

Since commissioning in 2025, Eco has worked through a range of technical and mechanical challenges associated with establishing consistent mill performance. With those early-stage issues largely addressed, the company is focused on optimizing operational assumptions and improving plant resiliency to support steady-state production. Continuing studies are being conducted to determine the optimal variables for maximizing concentrate grade and recovery.

In parallel, Eco and representatives of the company are in active discussions with potential buyers of gold concentrate in anticipation of marketable quantities being achieved.

JZR holds a 50-per-cent net profit interest in the Vila Nova project pursuant to a joint venture royalty agreement with Eco, providing direct exposure to future production and revenue generation.

Cautionary note

The samples referenced in this release are selective in nature and were collected as part of due diligence and proof-of-concept testing. They may not be representative of the tailings material as a whole. No mineral resource or reserve has been defined. Additional systematic sampling, quality assurance/quality control procedures and metallurgical testing are required to determine grade continuity, recoveries and economic viability.
