Bluejay Mining PLC Announces Drilling Commences at Hammaslahti

LONDON, UK / ACCESSWIRE / May 30, 2023 / Bluejay Mining plc (AIM:JAY) ('Bluejay' or the 'Company'), the AIM, FSE-listed and OTCQB traded exploration and development company with projects in Greenland and Finland, is pleased to announce that it has commenced a diamond drilling programme (the 'Programme') at the Company's 100% owned Hammaslahti Copper-Zinc-Lead-Gold-Silver ('Cu-Zn-Pb-Au-Ag') Project ('Hammaslahti' or the 'Project') located approximately 35 kilometres ('km') southeast of the city of Joensuu in Eastern Finland.

Highlights

• The first phase of the Programme will consist of 1500-2000 metres ('m') of diamond core drilling focussed on the "E-lode" ('E-lode'), a high-grade Cu-Zn-Pb-Au-Ag ore lode discovered in 2014 by Bluejay's 100% owned subsidiary, FinnAust Mining Finland Oy. The E-lode is located approximately 200m east from underground infrastructure of the former Hammaslahti mine and is comparable in grade and style of mineralisation to the ore-lodes that were mined historically.
• A series of planned drill fences will test the up-plunge and up/down-dip extensions of the E-lode, whilst also providing infill drilling, with the purpose of delineating a maiden resource estimate for this target.
• The previously announced discovery hole at the E-lode (refer to FinnAust Mining RNS dated: 21 July 2014) returned:
  • 8.65m grading 2.2% Cu, 2.0% Zn, 0.5 % Pb, 47.5 grams per tonne ('g/t') Ag, 0.5 g/t Au starting from 194.35m depth down-hole in semi-massive to massive sulphides hosted at the contact between strongly hydrothermally altered rocks and sulphidic black shales.
  • including 5.60m @ 3.2% Cu, 3.2% Zn, 81.1 g/t Ag, 0.9 g/t Au.
• The historical Hammaslahti mine was operated by the Finnish state mining company, Outokumpu Oy from 1971 to 1986. The open-pit and underground Hammaslahti mine, also held by Bluejay, produced a total of 7 million tonnes grading 1.16% Cu, 1.55% Zn, 0.59 g/t Au and 5.2 g/t Ag.
• The polymetallic mineralisation at Hammaslahti is interpreted to be a partially re-mobilised volcanogenic massive sulphide ('VMS') type deposit. All known previously mined ore lodes at Hammaslahti (namely, the Z-, N- and S-lodes) remain open down plunge to the South.
