Endomines Reports Encouraging High-Grade Intersections from the Pampalo Mine and Commences Further Underground Drilling Targeting Deep Extensions of the Deposit Endomines reported drill results from near-mine underground exploration drilling carried out at the end of 2021 at the Pampalo Gold Mine in Finland. The company further reports that, an underground drilling campaign targeting the deep extensions of the Pampalo deposit has commenced. The drilling program consisted of six (6) horizontal underground diamond drill holes for a total of 1 609 m. The drill holes were drilled to test underground exploration targets north and east of the Pampalo main mineralization, approximately 700 m below the surface. The aim of the drilling program was to find new mineable gold mineralizations in proximity to the existing mine infrastructure. Highlighted drill results include: T-1616 intersected 6.0 meters at 4.1 g/t gold, including 1.0 meters at 21.6 g/t gold and 2.7 meters at 7.1 g/t gold, including 0.7 meters at 17.3 g/t gold, T-1617 intersected 6.0 meters at 1.3 g/t gold, including 0.4 meters at 5.5 g/t gold and 2.8 meters at 2.1 g/t gold, T-1621 intersected 5.8 meters at 2.6 g/t gold, including 0.9 meters at 7.2 g/t gold. The overall results reported here clearly proves that the area near the mine is highly prospective for gold mineralization and the likeli hood of new discoveries is very high. Endomines will continue the near-mine exploration efforts in order to assess the full potential of the Pampalo mine area. The underground exploration drilling program had two main targets; the D-zone in the north and the deep extensions of the Pampalo East deposit. The D-zone is an under-explored area located immediately north of the Pampalo main orebody. The area is controlled by a large fold structure, where north-south trending lithological units (Pampalo) are turning towards west, providing favorable structures for gold mineralizations. The Pampalo East area is located immediately east of the Pampalo main ore body and it consists of several low-grade ore bodies that have been targets for mining in the Pampalo open pit. One of the most encouraging intersections in the drilling came from drill hole T-1617. The intersection 6.0 m at 1.3 g/t gold, including 0.4 m at 5.5 g/t gold is located approximately 70 meters north of the current mining area in so-called D-zone which is known to host gold mineralizations near the surface. More exploration drill holes are required to outline the size and grade of this mineralized lens. The best intersections of the program were received when drilling through potential extensions to the Pampalo main ore body. The intersection in drill hole T-1616 returned 6.0 m at 4.1 g/t gold, including 1.0 m at 21.6 g/t gold and 2.7 m at 7.1 g/t gold, including 0.7 m at 17.3 g/t gold from the N-lens. Drill hole T-1621 returned an intersection of 5.8 m at 2.6 g/t gold, including 1.0 m at 21.6 g/t gold from the S-lens. The S-lens between the 755 and 655 mine levels was not mined in 2017 due to the narrow nature of the ore body in this area. The company will now re-evaluate mining this area and is planning to drill more holes into it. Geological information from these new drill holes will be utilized in 3D structural modeling of the area and defining new exploration targets for further drill testing. A new drilling program targeting the deep extensions of the Pampalo deposit was commenced on 6th of April 2022. The program includes 4 000 meters of drilling and it covers the next 60 vertical meters down along the deposit. The purpose of the program is to increase reserves for mining. The program is estimated be completed in June 2022. All underground drilling has been carried out by Comadev Oy, using NQ2 tubes, resulting in core of 50.5mm in diameter. Drill hole locations, start azimuths and -dips have been surveyed by using mine survey equipment. Downhole survey of bearing and dip deviations have been done by using Reflex Gyro survey tool. All core has been oriented with Reflex ACT equipment. The drill cores have been logged by Endomines own personnel. The preparation and assaying of the underground drillings core samples have been carried out at Endomines laboratory in Pampalo, Finland or at the CRS Minlab Oy in Kempele, Finland. The sample procedure used at the laboratory was MPC's PAL1000 PULVERISE AND LEACH machine with AAS finishing. The used sample size was 500 g of crushed core. Ankündigung • Apr 01
Endomines AB (Publ) Reports Significant Increase in Gold Reserves At Pampalo Endomines AB (publ) announced a significant increase in gold reserves at its Pampalo mine in eastern Finland as of 31 December 2021. An update of the reserves and the resources at the mine and in other deposits along the Karelian Gold Line in Finland has been carried out as well as updates of the gold and silver resources for the company's gold projects in Idaho and Montana, USA. Gold reserves and resources at the Pampalo mine and resources along the Karelian Gold Line in Finland; The Pampalo mine was re-started in 2021 after being on care and maintenance since 2018. The updated ore reserve estimate for the deep extension area of Pampalo has a proven ore reserve of 161,000 tonnes with a grade of 3.55 g/t gold for a total 18,400 ounces gold. The updated ore reserve represents a 23 % increase in tonnes and 49 % increase in ounces when compared to the ore reserve estimate at 31 December 2020. The increase is due to the results of a drilling campaign completed in 2021. A total of 87 drill holes were drilled into the planned stoping area between the levels 755 and 815, and the results returned several spectacular high-grade intersectionsthat are incorporated into the present estimate. Most of the increase in tonnes and ounces is derived from a previously undrilled extension of the southern ore body. An additional inferred mineral resource of 122,000 tonnes with a grade of 5.24 g/t gold for 20 600 ounces gold has been reported for the area directly below the ore reserves (Pampalo Deep). The mineral resource remained approximately the same as on 31 December 2020, since no drill holes were drilled into this area in 2021. The deposit remains open at depth and the company is planning to continue underground drilling in 2022. There have been no changes in the reported mineral resources for other deposits along the Karelian Gold Line. An update and validation of the other mineral resource estimates is planned for 2022. The update will reflect increased geological understanding of the deposits and changes in the current market conditions. The estimates for the Pampalo mine and the resources along the Karelian Gold Line in Finland have been prepared according to the 2012 Australasian Code for Reporting of Mineral Resources and Ore Reserves (Joint Ore Reserve Committee - JORC-code).

Endomines AB (publ) Provides Production Guidance for the Year 2022 Endomines AB (publ) provided production guidance for the year 2022. When in full production Endomines expects annual gold production from the Pampalo mine to come in between 10.000 and 11.500 oz. Ankündigung • Feb 04
Endomines AB Provides Update on its Mining Operations in Finland and the United States Endomines provided an update on progress and mining development activities at its Finnish and US operations. Pampalo Finland: The Pampalo mine in eastern Finland was put on care and maintenance in 2018 when gold prices were at multiyear lows ($1250/oz). The ore lenses in the underground mine are open at depth and currently known lenses extend to the 855-mine level, and likely much below that. These areas and lower mining areas can be accessed by extending the existing decline thereby deepening the mine. An underground infill drilling program carried out in the summer/fall and targeted at the planned production levels between 755 and 855-mine levels returned several very high-grade gold intercepts. The mine deepening project was initiated in April 2021 and the decline reached the targeted 815-mine level in October. Mine development then started ahead of schedule in November and Pampalo processing plant started-up again at yearend. A mine development and stoping contract, covering all underground works for the ore mining was concluded with mining contractor Power Mining Oy. All own company personnel required to operate the mine and processing plant has been hired and trained. The grade of ore as well as tonnage coming from mine development is higher than what originally budgeted. The result is, more or less in line with the latest encouraging drilling program results. The the first mining stopes on the 815-mining level will come into production in February as previously announced. To date a total of 5,600 tonnes of high-grade ore from mine development averaging over 4 g/t has been stockpiled and will be fed to the processing plant in February. After the refurbishment of the mill was complete, the first batch of development ore was processed at the plant in December 2021. The processing plant was in general found to be in good condition and has performed very well from the beginning. Gold concentrate deliveries to Boliden started in January and the mill has now reached over 60 % of its throughput capacity. The planned mill ramp-up period is short and full throughput is expected to be achieved during the month of March. A gold concentrate sales agreement with Boliden covering the next 2 years, was signed in January 2022. Friday Idaho, US: Endomines re-started mining and milling activities at the Friday mine and Orogrande mill in Idaho, US in the fall of 2021, and ramp-up of the production has been ongoing since that time. Some 7,200 tonnes of ore has been mined and delivered to the mill and 5,300 tonnes has been processed. The mill is anticipated to operate near to its planned capacity in January. The milling has been hampered by challenges in recruiting mill personnel as well as sick leaves due to numerous Covid 19 cases. In mining the first stopes it has become evident that the gold mineralization is more irregular than had been previously interpreted resulting in sometimes large variances in ore tonnes and grades. As a result of this, more close spaced infill underground drilling is required to define ore stope boundaries for mine planning purposes. An initial underground drilling program to further define stopes has also confirmed this view. Accordingly, ore mining and underground development will now be temporarily halted at the mine while the company focuses exclusively on underground core drilling to outline the quality and quantity of ore. This will allow the company to design ore mining in a more cost-effective way, focus on operating cost reductions and make sure all mining activities are well aligned. The underground drilling program is planned to be carried out in the next 2-3 months and be targeted at defining ore boundaries. The drilling program will also test deeper areas where there are previous indications of high-grade gold mineralization. Depending on results the drilling may be extended. After completion of the underground drilling program, the ore models and ore resources will be updated and, if results are line with current expectation, mine ramp-up will continue. Due to a very small ore stockpile at the mill and the upcoming seasonal road closures preventing ore haulage from mine to process plant, ore processing will also be temporarily halted.

The new result reported here are supporting company's current view on the Pampalo deep extension and confirming the grades and widths used in the mine planning studies. The results will be added to company's database and a new resource estimate update will be completed once all the results have been received. The complete and final results of the drilling program will be released later this year. The Pampalo Gold Mine is located 45 kilometers northeast of the municipality of Ilomantsi in Eastern Finland. The Pampalo mine has been in production between 1996 and 1999 by Outokumpu Mining Oy and by Endomines between 2011 and 2018. The mine has produced 180 000 ounces (5 600 kg) of gold at an average grade of 3.6 g/t. Pampalo is an orogenic gold deposit located within the Archean Ilomantsi greenstone belt. The deposit is characterized by a series of sub-vertical, flattened, parallel pipes, plunging to the northeast and parallel to the local foliation and fold axis, implying a strong structural control of the mineralization. The mineralization is hosted by an intermediate pyroclastic unit, metamorphosed to greenschist - lower-amphibolite facies. All underground drilling has been carried out by Comadev Oy, using BQTK tubes, resulting in core of 40.7mm in diameter. Drill hole locations, start azimuths and -dips have been surveyed by using mine survey equipment. Downhole survey of bearing and dip deviations have been done by using Reflex Gyro survey tool. All core has been oriented with Reflex ACT equipment. The drill cores have been logged by Endomines own personnel. The preparation and assaying of the underground drillings core samples have been carried out at Endomines laboratory in Pampalo, Finland or at the CRS Minlab Oy in Kempele, Finland. The assay procedure used at the laboratory was MPC's PAL1000 PULVERISE AND LEACH machine with AAS finishing. The used sample size was 500 g of crushed core. Normal QA/QC (Quality Assurance/Quality Control) procedures have been adhered to on all the samples, with standards, blanks and duplicates routinely submitted as part of the sampling program. The quality of sample preparation, security integrity and chemical assays was equal to, or exceeded, current industrial standards and the requirements of the JORC-code.
