Inventus Mining Corp.: Inventus Reports 4.0 gpt Gold and 1.50 Metre Average for Trench 1 North Grade-Control Drilling and Provides Bulk Sample Update at the Pardo Gold Project

TORONTO, Sept. 23, 2025 (GLOBE NEWSWIRE) -- Inventus Mining Corp. (TSXV: IVS) ("Inventus" or the "Company") is pleased to report final results from grade-control drilling at its Trench 1 North Bulk Sample Site and provide an update on its bulk sampling at the 100%-owned Pardo Gold Project, located 65 km northeast of Sudbury, Ontario.

Highlights

• Results from the Trench 1 North Bulk Sample Site consisting of 28 grade-control drill holes had a weighted average grade and thickness of 4.00 gpt gold and 1.50 metres (Figure 1). The company intends to extract 10,000 tonnes at this location.
  
• Notable drill intercepts from the Trench 1 North Bulk Sample Site include:
  

12.61 gpt gold over 1.68 metres
13.88 gpt gold over 1.20 metres
10.54 gpt gold over 1.55 metres
11.53 gpt gold over 1.20 metres
9.38 gpt gold over 1.63 metres
6.53 gpt gold over 1.50 metres
5.75 gpt gold over 1.66 metres

• A total of 14,909 tonnes from two bulk samples have now been delivered to McEwen's Stock Mill.
  
• Extraction and delivery of the 007 North bulk sample with a drilled weighted average grade and thickness of 3.84 gpt gold and 1.82 metres (see news June 4, 2025) to McEwen's Stock Mill is complete for a total of 4,816 tonnes and processing is anticipated on or around October 13^th.
  
• Extraction and delivery of the Trench 1 Bulk Sample with a drilled weighted average grade and thickness of 4.10 gpt gold and 1.78 metres (see news July 7, 2025) to McEwen's Stock Mill is complete for a total of 10,093 tonnes and processing is anticipated in November.

Bulk Sample Area	Planned Bulk Samples Tonnes	Weighted Average Grade Control Drilling		Status
		Grade (g/t Au)	Thickness (m)
007 North	5,000	3.84	1.82	4,816 tonnes delivered to mill. Results in October.
Trench 1	10,000	4.10	1.78	10,093 tonnes delivered to mill. Results in December.
Trench 1 North	10,000	4.00	1.50	Grade-control drilling complete. Extraction October-November.

Drilling Update

Grade-control drilling at the Trench 1 North Site consisted of 52 shallow holes targeting the flat-lying gold mineralization to define a pit for bulk sampling. Holes were drilled on 7.5-metre centres to identify a zone of approximately 10,000 tonnes for the Company's third planned bulk sample. Assay results from 28 holes within an identified pit area had a weighted average grade and thickness of 4.00 gpt gold and 1.50 metres (see Figure 1, 2 and Table 2).

Bulk Sample Program Update

The 007 North Bulk Sample was delivered to McEwen's Stock Mill on August 6^th, for a total of 4,816 tonnes. The mill has now received all necessary permits to process bulk samples, and processing of the 007 North bulk sample is expected on or around October 13^th. Grade-control drilling from this site returned a weighted average grade and thickness of 3.84 gpt gold and 1.82 metres (see news June 4, 2025).

The Trench 1 Bulk Sample is now complete and was delivered to McEwen's Stock Mill on September 15^th, for a total of 10,093 tonnes and processing is anticipated in November. Grade- control drilling from this site returned a weighted average grade and thickness of 4.10 gpt gold and 1.78 metres (see news July 7, 2025).

Additional updates and results of the Company's Bulk Sample Program will be provided as they become available.

Wesley Whymark, President and Head of Exploration comments: "The Trench 1 North results are another strong validation of the high-grade, near-surface gold system at Pardo demonstrating the consistency of grade from each bulk sample site. We are positioned for an exciting period ahead as the gold price continues to climb and processing is set to begin on our 14,909 tonnes of bulk sample material currently at the mill. While we remain patient for milling to commence, these upcoming results will be instrumental in demonstrating the grade and economics of surface mining at Pardo and the project's potential to evolve into a low-cost scalable mining operation in Ontario's Sudbury district."

Qualified Person

The Qualified Person responsible for the technical content of this news release is Inventus' President and Head of Exploration, Wesley Whymark, P.Geo., who has reviewed and approved the technical disclosure in this news release on behalf of the Company.

Technical Information

Drill core samples collected by Inventus and described in this news release were subject to a variety of QA/QC protocols. PQ Size drill core was placed in core boxes by the contracted drill crew and then transported by Inventus personnel to a secure processing facility in Sudbury, Ontario. The core was then reviewed with core metreage blocks checked to verify core integrity, recovery and geologically logged with samples marked. Whole core samples were then photographed and inserted into a clean plastic bag with a sample tag. Certified reference materials were inserted into the sample stream at a rate of no less than 10%. Samples were then transported in secure sealed bags with security tags for preparation and assay by MSA Labs in Val d'Or, Quebec. All samples reported were crushed in their entirety to 80% passing 2 mm. A subsample comprising 2 kg was riffle split and pulverized to 85% passing 75 microns (-200 mesh). The 2kg pulverized subsample is then riffle split into one 300- to 500-g jar for gold analysis by PhotonAssay. MSA Labs is an ISO 17025:2017 accredited geochemical testing laboratory.

Forward-looking information in this news release includes, but is not limited to, the Company's objectives, goals or future plans, statements, exploration results, potential mineralization, the estimation of mineral resources, exploration and mine development plans, timing of the commencement of operations and estimates of market conditions. Factors that could cause actual results to differ materially from such forward-looking information include, but are not limited to the failure to identify mineral resources, failure to convert estimated mineral resources to reserves, the inability to complete a feasibility study which recommends a production decision, the preliminary nature of metallurgical test results, delays in obtaining or failures to obtain required governmental, environmental or other project approvals, political risks, inability to fulfill the duty to accommodate First Nations and other indigenous peoples, uncertainties relating to the availability and costs of financing needed in the future, changes in equity markets, inflation, changes in exchange rates, fluctuations in commodity prices, delays in the development of projects, capital and operating costs varying significantly from estimates and the other risks involved in the mineral exploration and development industry, and those risks set out in the Company's public documents filed on SEDAR+. Although the Company believes that the assumptions and factors used in preparing the forward-looking information in this news release are reasonable, undue reliance should not be placed on such information, which only applies as of the date of this news release, and no assurance can be given that such events will occur in the disclosed time frames or at all.
