Gold in one of four holes as Nya Gilleberget is fully reported: the 28 metre zone remains open and the Company will drill two new holes towards it this autumn

Background

The programme was carried out between April and May 2026 and comprised four core drill holes totalling 989.9 metres. Core drilling recovers a whole cylinder of rock from the hole, which is then cut lengthwise and assayed, so that grades can be tied to an exact depth. The holes targeted two areas where the bedrock is magnetic in a way that can indicate mineralisation (magnetic anomalies). GB202601, GB202602 and GB202604 were drilled at the north-western target. GB202603 was drilled at the south-eastern target, approximately 4.5 kilometres south-east and never previously drill tested.

The assay results from GB202601 were announced on 26 June 2026, stating that results from the remaining holes were expected in August. The Company thereby delivers, on time, the milestone stated in the interim report for the second quarter.

Comment from the CEO

"We drilled four holes at two targets and got a broad gold hit in one of them, 28 metres in the core. That outcome was better than we had expected. What also interests me are the boulders in the south-eastern area, because they point back towards bedrock we have not yet investigated. It is an interesting lead to follow, and we now know both where to look next and where not to look. We have decided to run a drilling programme this autumn. We are planning two new drill holes, 600 metres in total, and the first will give us information some distance from the gold intersection. Stortjärnhobben remains the Company's main project."

Results

Four holes were drilled at two areas. Gold was found in one of them, GB202601, and that was reported on 26 June 2026. The three holes reported now, GB202602, GB202603 and GB202604, contain no interval to report. The highest individual sample value in the three holes is 0.64 grams of gold per tonne, in GB202602. All assay values are listed in Appendix 1.

The north-western target. GB202602 and GB202604 were drilled to test the rock around the zone that GB202601 intersected. GB202604 was drilled in the opposite direction from its own starting point at surface, the collar, and therefore investigated the rock on the other side of it. Neither of the two holes came closer than one hundred metres to the midpoint of the zone, and neither reached the level at which the zone lies. They therefore tested rock volumes other than the one the zone lies in. That they returned no gold says neither that the zone continues nor that it ends. The distances and levels are reported in Appendix 3.

The gold zone of 28.05 metres at 2.30 grams of gold per tonne in GB202601 is reported unchanged since 26 June 2026. It is neither larger nor smaller than the Company stated then, and it is still not bounded, that is, not enclosed by drill holes on all sides so that its extent is known. To learn which way it dips and runs, the Company needs to drill within about one hundred metres of GB202601. The Company has decided to do so. Two new core drill holes totalling 600 metres are budgeted for the autumn of 2026. The first is aimed at the rock some distance from the gold intersection, to show how far the zone runs. The second will be planned on what the first one shows.

The south-eastern target, the drill hole. The area had never been drilled before. GB202603 was terminated at 251.15 metres rather than the planned 300, the drilling having by then passed the pyrrhotite zone that accounts for the magnetic anomaly the hole was aimed at. Pyrrhotite is a magnetic iron sulphide mineral, which is why it shows up in airborne surveys. The highest gold grade in the hole is 0.14 grams per tonne.

The south-eastern target, the boulder prospecting. Boulder prospecting means searching for loose boulders at surface and assaying them. It is a different exploration method from core drilling and answers a different question. Eleven boulders have been assayed. The three richest assay 10.4, 4.22 and 1.77 grams of gold per tonne and lie within 150 metres of each other. The remaining eight assayed 0.67 or lower. The boulders are loose stones on the ground. Where in the bedrock they came from, and how much gold is there, cannot be determined without drilling.

The ice sheet here moved from north-west to south-east, carrying rock with it. The three richest gold-bearing boulders lie 844 to 987 metres south-east of GB202603. The bedrock they once broke away from therefore lies somewhere to the north-west of them. The source of the mineralised boulders has not been found. To find it, the Company needs to search for more boulders and sample the soil cover in that direction. Only then is it clear where drilling would be worthwhile.

Lengths are measured along the drill hole, not straight through the mineralisation. The true width of the zone cannot be stated until it has been drilled from more directions, and that figure is therefore not given. The grades are calculated in the same way as on 26 June 2026. Collar data, all assay values, the boulder coordinates, sampling, quality control and the calculation basis are reported in Appendices 1 to 3.

Qualification

The reported assay results are Exploration Results, that is, individual findings. They do not show that the gold can be mined profitably, and there is no guarantee that further exploration will lead to the definition of a Mineral Resource. Stortjärnhobben is the Company's main project.

About the Company

Lappland Guldprospektering AB (publ) is a Swedish exploration company focused on gold in Sweden. The Company's main project is Stortjärnhobben in southern Lapland, where an Inferred Mineral Resource of 4.6 tonnes of gold has been reported according to the PERC Reporting Standard¹.

In addition to Stortjärnhobben, the Company holds seven exploration permits for gold and two for copper, zinc and silver. The Company is listed on the Spotlight Stock Market under the ticker LGOLD B, with its registered office in Stockholm and head office in Skellefteå.

¹ PERC refers to the PERC Reporting Standard (2021 edition), the pan-European standard for the reporting of Mineral Resources and Mineral Reserves. The Inferred Mineral Resource at Stortjärnhobben amounts to 4.6 tonnes of gold in 2.65 million tonnes of ore at 1.73 grams of gold per tonne. Inferred means that quantity and grade are estimated with low geological confidence. Cut-off grade: 0.8 grams of gold per tonne. Top-cut for individual high grades: 20 grams of gold per tonne. That Mineral Resource was reported by Lazaros Dalampiras, MAusIMM CP(Geo). Stortjärnhobben is not affected by this press release.
