Kodiak Announces Filing Of NI 43-101 Technical Report: Initial Mineral Resource Estimate On Four Of Seven Mineralized Zones At The MPD Copper-Gold Project

(MENAFN- Newsfile Corp) Vancouver, British Columbia--(Newsfile Corp. - August 12, 2025) - Kodiak Copper Corp. (TSXV: KDK) (OTCQB: KDKCF) (FSE: 5DD1) (the " Company " or " Kodiak ") today announces that it has filed an independent technical report (the "Report") on SEDAR+ prepared in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") in support of initial Mineral Resource estimates for four deposits on the Company's 100%-owned MPD copper-gold project in southern British Columbia. Mineral Estimates on three additional mineralized zones are being developed and are anticipated in the second half of 2025 (see news release June 25, 2025).

Highlights

• Sizable initial copper-gold Mineral Resource estimate ("MRE") prepared for four of seven mineralized zones outlined to date at MPD: Gate, Ketchan, Man and Dillard. Figure 1

• Indicated Mineral Resource: 56.4 million tonnes (Mt) grading 0.42% copper equivalent (CuEq) for 385 million pounds (Mlb) of copper (Cu) and 0.25 million ounces (Moz) of gold (Au) . Table 1

• Inferred Mineral Resource: 240.7 million tonnes (Mt) grading 0.33% copper equivalent (CuEq) for 1,291 million pounds (Mlb) of copper (Cu) and 0.96 million ounces (Moz) of gold (Au) . Table 1

• The MRE is defined using open pit design shells to constrain the Resource models and a cut-off grade of 0.2% CuEq . Sensitivity cases using lower cut-of grades have significantly higher tonnages and metal contents. Table 2

• Mineralization remains open for expansion within and beyond the MRE pit shells , in multiple directions and at depth.

• The full MRE for all seven mineralized zones at MPD is planned for completion in Q4 with the addition of three further mineralized zones (West, Adit and South), where confirmation and infill drilling is currently under way as part of the Company's 2025 exploration program (see news release June 18, 2025 ).

• The higher-grade, near surface mineralization identified at the West, Adit and South zones has the potential to make an important contribution to the full MRE . Figure 1

• The Report is available on SEDAR+ and on the Company's websit .

Initial Mineral Resource Estimate

The drill hole density in the central part of the Gate Zone was sufficient to develop a 56.4 Mt Indicated Resource grading 0.42% CuEq. Inferred Resources at the Man, Dillard, Ketchan and Gate zones total 240.7 Mt with an average grade of 0.33% CuEq (see Table 1). The Inferred Resource at Gate is peripheral to the Indicated Resource. Figure 2 shows the MRE pit shells that support the Reasonable Prospects of Eventual Economic Extraction (RPEEE).

Table 1: MPD Initial Mineral Resource Estimate

MPD Initial Mineral Resource Estimate - Part 1 (4 of 7 zones)
Zone	Resource Category	Tonnes	Average Grade	Metal Content
		(Mt)	Cu (%)	Au (g/t)	Ag (g/t)	CuEq (%)	Cu (Mlbs)	Au (Moz)	Ag (Moz)	CuEq (Mlbs)
Gate	Indicated	56.4	0.31	0.14	1.18	0.42	385	0.25	2.14	522
Gate	Inferred	114.5	0.27	0.13	1.07	0.36	681	0.48	3.94	909
Man	Inferred	8.3	0.17	0.30	0.56	0.37	31	0.08	0.15	68
Dillard	Inferred	51.9	0.20	0.09	0.39	0.26	229	0.15	0.65	298
Ketchan	Inferred	66.0	0.24	0.12	1.09	0.33	349	0.25	2.31	480
Total Indicated	56.4	0.31	0.14	1.18	0.42	385	0.25	2.14	522
Total Inferred	240.7	0.24	0.12	0.91	0.33	1,291	0.96	7.05	1,754

Notes: 1. The Mineral Resources were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum(CIM), Definition Standards for Mineral Resources and Reserves, as prepared by the CIM Standing Committee and adopted by CIM Council.

2. A cut-off grade of 0.2% CuEq was applied to the MRE models within the pit shells.

3. Pit shell optimization used average recoveries derived from metallurgical test work of Cu 82%, Au 60% and Ag 54%, exchange rate of 1.35 CAD:USD, mining cost of C$2.3/t, process cost of C$8.5/t, and pit slope of 45 degrees.

4. Copper equivalence (CuEq) and constraining pit shells assume metal prices (US$) of: $4.2/lb copper, $2,600/oz gold, $30/oz silver.

5. The copper equivalency equation used is: CuEq(%) = Cu(%) + Au(g/t) x 0.6606 + Ag(g/t) x 0.0069

6. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resources will be converted into mineral reserves in the future. The MRE may be materially affected by considerations including, but not limited to, permitting, legal, sociopolitical, environmental issues, market conditions or other factors.

7. All figures are rounded to reflect the relative accuracy of the estimate. Totals may not sum due to rounding as required by reporting guidelines.

Sensitivity Cut-off Grades

In addition to the base case cut-off grade ("COG") of 0.2% CuEq a range of cut-off grades from 0.12% to 0.22% CuEq were applied to the Resource models to evaluate the potential effect on tonnage, grade and metal content (Table 2). Lower cut-off grade sensitivity cases demonstrate a notable increase in tonnage and in-situ metal, with a decrease in average grades. The values in the COG sensitivity cases are for comparison purposes only and should not be considered Mineral Resources.

MPD Initial Mineral Resource Estimate & Cut-Off Grade Sensitivity Scenarios
Cut-Off Grade	Indicated	Inferred
(CuEq %)	Tonnes (Mt)	CuEq (%)	CuEq (Mlbs)	Tonnes (Mt)	CuEq (%)	CuEq (Mlbs)
0.22	50.6	0.44	491	204.5	0.35	1,578
0.20	56.4	0.42	522	240.7	0.33	1,754

0.12	82.4	0.33	600	435.6	0.25	2,415

Notes: 1. Copper equivalence (CuEq) assumes metal prices (US$) of: $4.2/lb copper, $2,600/oz gold, $30/oz silver.

2. CuEq is based on average recoveries derived from metallurgical test work as applied in the pit optimization process. Average recoveries are: Cu 82%, Au 60% and Ag 54%.

3. The copper equivalency equation used is: CuEq(%) = Cu(%) + Au(g/t) x 0.6606 + Ag(g/t) x 0.0069
