Press release (PDF)

Endomines AB, stock exchange release 12 August 2021 at 09:15 CEST

Endomines is pleased to announce the first results from the 2021 underground drilling program underway at the Pampalo Gold Mine in Finland. The underground drilling program is a part of the mine re-opening and deepening project started in February 2021.

To date, fifty-six (56) drill holes for a total of 4,107 m of the 8,000 m drilling program is completed and assay results have been received for thirty nine (39) diamond drill holes for a total of 2,847 m. All the reported results are from infill drilling targeted at the planned production area between the 755 and 855 mine levels.

Highlighted drill results include:

  • T-1670 intersected 3.9 meters at 151.4 g/t gold (9.6 g/t when capped at 20 g/t), including 0.8 meters at 747.7 g/t gold
  • T-1626 intersected 4.3 meters at 92.9 g/t gold (7.6 g/t when capped at 20 g/t), including 1.1 meters at 357.6 g/t gold
  • T-1642 intersected 4.0 meters at 56.6 g/t gold (12.8 g/t when capped at 20 g/t), including 1.2 meters at 157.7 g/t gold
  • T-1675 intersected 6.4 meters at 15.5 g/t gold (4.5 g/t when capped at 20 g/t), including 1.1 meters at 86.9 g/t gold
  • T-1672 intersected 5.2 meters at 14.8 g/t gold (8.1 g/t when capped at 20 g/t), including 1.1 meters at 52.6 g/t gold

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 most interesting drill intersections are presented in the figure below and complete drill results area presented in Table 1.

Background

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.

Drilling technical

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.

Assay and QA/QC procedures

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.
