VANCOUVER, British Columbia, March 03, 2025 (GLOBE NEWSWIRE) -- Westhaven Gold Corp. (TSX-V:WHN) is pleased to report the completion of an Updated Preliminary Economic Assessment (“PEA”) at its 100% owned 41,634-hectare Shovelnose Gold Property (the “Property”) located within the prospective Spences Bridge Gold Belt (“SBGB”), which borders the Coquihalla Highway 30 kilometres south of Merritt, British Columbia. The PEA outlines a robust, low-cost, rapid pay-back, high margin, 11.1 year underground gold mining opportunity and is based on updated mineral resources that include contributions from the South, Franz and FMN zones.
At a gold price of US$2,400/oz and an exchange rate of C$1.00 to US$0.72, the Shovelnose base case estimate (the "Base Case") generates an after-tax net present value (NPV) at a 6% discount rate of $454 million and an internal rate of return (IRR) of 43.2%. The proposed mine will operate over an initial 11.1 year mine-life with average annual life-of-mine gold production of 56,000 ounces. Initial capital expenditure to fund construction and commissioning is estimated at $184 million, with a life-of-mine capital cost of $379 million and a payback period of 2.1 years. The all-in sustaining costs (as defined per World Gold Council guidelines, less corporate G&A) are estimated to be US$836 per ounce of gold produced.
Summary Table - Economic Sensitivity to Long Term Gold Price
| Long Term Metal Price Variability | Corresponding Gold Price | After Tax NPV (at 6%) | After Tax IRR | | (percentage change) | US$/ounce | CDN $ millions | (%) | | - 20% | 1,920 | 284.3 | 30.4 | | - 10% | 2,160 | 369.1 | 36.9 | | base case | 2,400 | 453.7 | 43.2 | | + 10% | 2,640 | 538.3 | 49.5 | | + 20% | 2,880 | 622.8 | 55.7 |
Gareth Thomas, President & CEO, comments: “Westhaven’s flagship Shovelnose Gold Property is ideally situated, in close proximity to roads, power and infrastructure in a tier 1 mining jurisdiction. Production contribution from both Franz and FMN provide valuable ounces that bring gold production forward in the schedule resulting in payback of initial capital costs in just 2.1 years. Our intention is to continue to advance this cornerstone project in parallel with our ongoing exploration efforts to further expand the gold-silver mineral inventory on this highly prospective land package. The next steps towards rapidly advancing development include further de-risking initiatives such as continued environmental baseline studies, permitting requirements, along with other cost and technical requirements.”
The Company cautions that the results of the PEA are preliminary in nature and include Inferred Mineral Resources that are considered too speculative geologically to have economic consideration applied to them to be classified as Mineral Reserves. There is no certainty that the results of the PEA will be realized. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

Mineral Resources, Updated PEA Preparation and Results
The previous public Mineral Resource Estimate (“MRE”) for the South Zone was carried out by P&E Mining Consultants Inc. (“P&E”) with an effective date July 18, 2023. The current underground MRE is reported herein. All drilling and assay data were provided by Westhaven, in the form of Excel data files. The GEOVIA GEMS™ V6.8.4 database compiled by P&E for the February 28, 2025 MRE consisted of 355 surface drill holes, totalling 121,971 metres. A total of 145 drill holes (50,714 metres) were intersected by the Mineral Resource wireframes used in this PEA.
P&E validated the Mineral Resource database in GEMS™ by checking for inconsistencies in analytical units, duplicate entries, interval, length or distance values less than or equal to zero, blank or zero-value assay results, out-of-sequence intervals, intervals or distances greater than the reported drill hole length, inappropriate collar locations, survey and missing interval and coordinate fields. Some minor errors were identified and corrected in the database. The QPs are of the opinion that the supplied database is suitable for Mineral Resource estimation.
Block models were constructed using GEOVIA GEMS™ V6.8.4 modelling software and consist of separate model attributes for estimated Au, Ag and AuEq grade, rock type (mineralization domains), volume percent, bulk density, and classification. The Mineral Resource was classified as Indicated and Inferred based on the geological interpretation, variogram performance and drill hole spacing. The QPs also consider mineralization at the South, Franz and FMN Zones to be potentially amenable to underground mining methods. The revised MRE used for this Updated PEA is reported with an effective date of February 28, 2025 and is tabulated in Table 1.

A financial model was developed to estimate the Life of Mine (“LOM”) plan and considered only underground mining of Mineral Resources at the South, Franz and FMN Zones. Other known gold-silver mineralization at the Shovelnose Gold Property, currently being evaluated by Westhaven, are not included.
The LOM plan covers a 13.1-year period (2 years pre-production and 11.1 years of production). Currency is in Q1 2025 Canadian dollars unless otherwise stated. Inflation has not been considered in the financial analysis.
The Updated PEA outlines a production mine life of 11.1 years with average annual production of 56,000 ounces gold and 312,000 ounces silver at average respective cash costs and all-in sustaining costs ("AISC") per ounce gold equivalent of $1,161(US$836). The PEA considers the payable recovery of 637,000 oz gold and 3,562,000 oz silver from an underground operation, at average respective mine production grades of 5.26 g/t and 32 g/t.
Revenue
The commercially saleable product generated by the Project is a gold/silver doré. Westhaven would be paid once the doré has been delivered to a smelter and refinery, off-site.
The NSR payables were based on the following parameters: Dore Payable (Includes refining and smelting) Au 99% Ag 90%
The CDN$/US$ exchange rate used in the PEA is 0.72.
Subtotal Revenue Au (US$) $1,529M Ag (US$) $100M Net revenue CDN$ $2,201M
The revenue generation by the Shovelnose Project, on a yearly basis, is presented in Table 2.

Cash Flow Sensitivity Analysis
The following after-tax cash flow analysis was completed:
Net Present Value (“NPV”) (at 5%, 6%, 7%, 8%, 9% and 10% discount rates). Internal Rate of Return (“IRR”). Payback period.
The summary of the results of the cash flow sensitivity analysis is presented in Table 4
| Table 4 Base Case Cash Flow Sensitivity Analysis | | | | | Description | Discount Rate | Units | Value | | Undiscounted After-Tax CF | 0% | (M$) | 785 | | Internal Rate of Return | % | 43.2 | | | After-Tax NPV at | 5% | (M$) | 496 | | Base Case 6% | (M$) | 454 | | | 7% | (M$) | 415 | | | 8% | (M$) | 380 | | | 9% | (M$) | 348 | | | 10% | (M$) | 319 | | | After-Tax Total Project Payback (including pre-production) | Years | 4.1 | |
The Project was evaluated on an after-tax cash flow basis which generates a net undiscounted cash flow estimated at $785M. This results in an after-tax IRR of 43.2% and an after-tax NPV of $454 M when using a 6% discount rate. In the base case scenario, the Project has a payback period of 4.1 years from the start of the Project. The average life-of-mine cash cost is $872/oz AuEq (US$628/oz AuEq), at an average operating cost of $142/t processed. The average life-of-mine all-in sustaining cost (“AISC”) is estimated at $1,161/oz AuEq (US$836/oz AuEq).
Sensitivity Analysis
Project risks can be identified in both economic and non-economic terms. Key economic risks were examined by running cash flow sensitivities to: gold metal price; silver metal price; gold process plant head grade; gold metallurgical recovery; operating costs; and capital costs.
Each of the sensitivity items were varied up and down by 10% and 20% to assess the effect they would have on the NPV at a 6% discount rate. The value of each parameter, at 80%, 90%, 100% base case, 110% and 120%, is presented in Table 5.
| Table 5 | | | | | | | NPV Sensitivity Parameter Values | | | | | | | Parameter | 80 % | 90 % | 100 % | 110 % | 120 % | | Au Metal Price US$/oz | 1,920 | 2,160 | 2,400 | 2,640 | 2,880 | | Ag Metal Price US$/oz | 22.40 | 25.20 | 28.00 | 30.80 | 33.60 | | Au Head Grade g/t | 4.21 | 4.73 | 5.26 | 5.79 | 6.31 | | Au Met Recovery % | N/A | 82.4% | 91.5% | N/A | N/A | | Capex $M | 304 | 342 | 379 | 417 | 455 | | Opex $M | 471 | 530 | 589 | 648 | 707 |
The resultant after-tax NPV @ 6% values of each of the sensitivity parameters at 80% to 120% are presented in Table 6.
