Endomines reports high-grade underground drill results from Pampalo
Endomines reports drill results from the underground core drilling program carried out in the spring-summer 2023 at the Pampalo Gold Mine. The drill program consisted of forty-seven diamond drill holes for a total of 4 487 m. Drill holes were targeted to the area between the 875 and 955 mine levels, representing the next 80 vertical meters below the current production area.
Highlighted drill results include:
- T-1856 intersected 6.4 meters at 20.0 g/t gold (5.4 g/t when capped at 20 g/t), including 0.7 meters at 163.0 g/t gold
- T-1833 intersected 4.7 meters at 22.3 g/t gold (14.4 g/t when capped at 20 g/t)
- T-1869 intersected 1.8 meters at 48.0 g/t gold (9.5 g/t when capped at 20 g/t), including 0.8 meters at 109.0 g/t gold
- T-1844 intersected 6.7 meters at 12.1 g/t gold (10.4 g/t when capped at 20 g/t), including 1.0 meters at 31.4 g/t gold
- T-1864 intersected 7.6 meters at 7.9 g/t gold (7.8 g/t when capped at 20 g/t), including 1.2 meters at 20.4 g/t gold
The underground drill results reported here are showing that the ore lodes currently being mined above 875 mine level are continuing to the deeper levels with approximately similar grades and widths. The infill core drilling program (6 000 m) for the same area commenced in mid-August and will be completed by the end of the year. In addition, extending the decline from the 875 level to the 955 level is in progress and it is currently progressing at the 897 level.
The most interesting new drill intersections from infill drilling are presented in the figure below and complete drill results area presented in Table 1.

Note: Coordinates are in local Mine Grid. A lower cut-off of 1.0 g/tonne Au has been used for all intervals. *Assay results capped at 20 g/t gold (Based on the geostatistical analysis and the recorded production data from the mine).
Drilling technical
All underground drilling has been carried out by Comadev Oy, using BQTK tubes, resulting in core of 40.7 mm 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 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.
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.
