Endomines reports that it is encouraging high-grade intersections at the Pampalo Mine and is commencing further underground drilling targeting deep extensions of the deposit

Endomines ABstock exchange release 2n/a May 2022 to 3:00 p.m. CEST

endomines is pleased to announce the results of underground exploration drilling in the vicinity of the mine 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 begun.

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 to the north and east of the main Pampalo mineralization, approximately 700m below surface. The objective of the drilling program was to find new mineable gold mineralization near the existing mining infrastructure.

Highlighted drill results include:

  • T-1616 intersected 6.0 meters at 4.1 g/t gold, including 1.0 meter 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 prove that the area near the mine is very promising for gold mineralization and the likelihood of further discoveries is very high. endomines will continue exploration efforts near the mine to assess the full potential of the Pampalo mining area.

The most interesting new drill intersections from the infill drilling are shown in the figure below and the full area of ​​drill results presented in Table 1.

The underground exploration drilling program had two main targets; the D zone to the north and the deep extensions of the Pampalo East deposit. Zone D is an under-explored area located immediately north of the main Pampalo ore body. The area is controlled by a large folded structure, where the north-south trending lithological units (Pampalo) turn west, providing favorable structures for gold mineralization. The Pampalo East zone is located immediately to the east of the main Pampalo orebody and consists of several low-grade orebodies that have been mined in the Pampalo open pit mine.

One of the most encouraging intersections in the hole came from hole T-1617. The intersection of 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 the area known as D which is known to contain gold mineralization near the surface. Further exploration drilling is required to determine the size and grade of this mineralized lens.

The program’s best intersections were obtained while drilling through potential extensions of the main Pampalo ore body. The intersection of 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 of gold, including 0.7 m at 17.3 g/t of gold from the N-lens. Hole T-1621 intersected 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. Mine levels 755 and 655 were not mined in 2017 due to the narrow nature of the ore body in this area. The company will now reevaluate the mining of this area and plans to drill more holes there.

The geological information from these new drill holes will be used in the 3D structural modeling of the area and the definition of new exploration targets for further drilling tests.

A new drilling program targeting the deep extensions of the Pampalo deposit began on 6 April 2022. The program includes 4,000 meters of drilling and covers the next 60 vertical meters along the deposit. The purpose of the program is to increase reserves for mining. The program should be completed in June 2022.

Background

The Pampalo Gold Mine is located 45 kilometers northeast of the municipality of Ilomantsi in Eastern Finland. The Pampalo mine was in production between 1996 and 1999 by Outokumpu Mining Oy and by endomines between 2011 and 2018. The mine 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 in the Archean Ilomantsi greenstone belt. The deposit is characterized by a series of parallel, flattened, subvertical, northeast-dipping pipes parallel to the local axis of foliation and folding, implying strong structural control of the mineralization. The mineralization is hosted in an intermediate pyroclastic unit, metamorphosed to greenschist-lower amphibolite facies.

Drilling technique

All underground drilling was carried out by Comadev Oy, using NQ2 tubing, resulting in a 50.5mm diameter core. Drill hole locations, starting azimuths and dips were surveyed using mine surveying equipment. A downhole survey of bearing and dip deviations was performed using the Reflex Gyro survey tool. The entire core was oriented with Reflex ACT equipment.

Analysis and QA/QC procedures

Drill cores were recorded by endomines own staff. The preparation and analysis of underground drilling cores were carried out at endomines laboratory in Pampalo, Finland or at the CRS Minlab Oy in Kempele, Finland. The sampling procedure used in the laboratory was MPC’s PAL1000 PULVERISE AND LEACH machine with AAS finish. The sample size used was 500 g of crushed kernel.

Standard QA/QC (Quality Assurance/Quality Control) procedures were followed for all samples, with standards, blanks and duplicates consistently submitted as part of the sampling program. The quality of sample preparation, safety integrity, and chemical analyzes were equal to or better than current industry standards and JORC code requirements.
