LONDON, UK / ACCESSWIRE / March, 28 2023 / Bluejay Mining plc, the AIM, FSE listed and OTCQB traded exploration and resource development company with projects in Greenland and Finland, is pleased to announce that a short follow-up drill programme has commenced at the Enonkoski Nickel-Copper-Cobalt ('Ni-Cu-Co') Project ('Enonkoski' or the 'Project') in eastern Finland as part of the Joint Venture ('JV') and earn-in agreement with Rio Tinto Exploration Finland Oy ('Rio Tinto') announced 10 November 2020.

The short follow-up diamond drilling programme at Enonkoski is planned to consist of a single drill hole with a planned depth of 400 metres ('m') at the Laukunlampi intrusion located approximately 1 kilometre ('km') south-east of the historic Laukunkangas Ni-Cu-Co mine. Two drill holes for a total of 951.1m were completed at the Laukunlampi target in January, followed by downhole electro-magnetic ('DHEM') and three component ('3C') magnetic surveys on both new drill holes, which were completed during February. For further details and analytical results refer to our earlier RNS dated 27 March 2023 (titled: "Encouraging drilling results from the Enonkoski Ni-Cu-Co Joint Venture Project with Rio Tinto").

Based upon the encouraging results from the diamond drilling programme in January and subsequent geological and geophysical modelling, the JV have decided to proceed with drill testing a high-priority drill target within the Laukunlampi intrusion whilst drill rig availability allows. The new hole (ENON0029) currently in progress, is collared 435m to the north-northwest of ENON0028 (Figure 2, Table 1). The objective of the current drill hole is to test the current geological model which indicates that the pyroxenitic units (the most favourable rock type within the Laukunlampi intrusion to host Ni-Cu-Co mineralisation) continue towards the north-west. In addition, the drill hole will test a NNW-SSE trending and NNW plunging magnetic anomaly that is coincident with an airborne electromagnetic ('EM') conductor that has not previously been drill tested. Very limited drilling has been conducted in the north and north-western parts of the Laukunlampi intrusion, in the direction of the Laukunkangas Ni-Cu-Co mine. The intrusion remains open in this direction. The increasing sulphide content and Nickel ('Ni') tenor encountered in the previously announced drill hole ENON0028 also support that drilling along strike to the northwest of this hole may lead to the discovery of sulphide droplet zones with higher Ni grades and ultimately to ore grade semi-massive to massive sulphides.

Thomas Levin, COO of Bluejay subsidiary FinnAust Mining Finland Oy ('FinnAust'), commented: "Given the unusually high demand for diamond drill rigs throughout Finland at present, I am delighted that our drilling contractor has been able to provide us with a rig for a short time window, allowing us to complete this high priority follow up drill hole in the Laukunlampi intrusion. The drilling and downhole geophysics completed in January-February were completed significantly under budget, which is a testament to FinnAust's ability to operate cost effective exploration programmes in Finland and has allowed us to add this extra drill hole within the current stage of JV funding for the Enonkoski Project.

"The current hole tests a NNW-SSE trending and NNW plunging magnetic anomaly that is coincident with an untested airborne EM conductor, as well as dense gravity response that supports the presence of favourable pyroxenites. We have several independent geophysical proxies aligning, which in combination with the increasing sulphide content and nickel tenor observed as we move to the northwest of the intrusion, makes for a compelling drill target".

Former historical drill holes are also displayed. Colours on drill-holes represent different lithologies. The modelled pyroxenite (red solid) and the mafic-ultramafic Laukunlampi intrusive (green solid) are both open towards north and north-west towards an area with no historic drilling. The NNW-SSE trending and NNW plunging magnetic model (black solid rectangles) is coincident with a local conductor also untested by drilling. The distance between hole collars of ENON0028 and the current hole ENON0029 is 435m.

Further information on the Laukunlampi mafic-ultramafic intrusion

The Laukunlampi intrusion is located approximately 1.5 km along strike to the south-east of the historic Enonkoski (Laukunkangas) nickel-copper-cobalt mine. The Laukunkangas deposit was discovered in 1969, although the high-grade ore was only discovered in 1980. The mine was operated between 1985 to 1994 by Outokumpu Oy. The Laukunkangas ore deposit occurred as many separate ore lodes hosted within the ultramafic-mafic rocks of the eastern and northern portions of the Laukunkangas intrusion. The ore types varied from massive to semi-massive sulphide ores to sulphide droplets zones plus strong sulphide dissemination hosted in peridotite and weak sulphide dissemination hosted in norite. Typical ore minerals were pyrrhotite, pentlandite and chalcopyrite. Some of the richest ore occurred as off-set ore lodes outside of the intrusion, within the mica gneiss or graphitic gneiss wall-rocks. A total of 6.7 million tonnes at 0.78% Ni and 0.22% Cu was mined from the Laukunkangas mine. The off-set massive ore graded over 5%, with Cu grades of up to 2% and Co grades of up to 0.3%, whilst the lower-grade disseminated ore typically contained 0.3-0.4% Ni (Geological Survey of Finland, 2020).

Strong similarities between both the Laukunkangas intrusion (that hosts the former mine of the same name) and Laukunlampi intrusions have been recognised. Disseminated sulphides and pyrrhotite-chalcopyrite-pentlandite droplets analogous to the droplet ore at the Laukunkangas mine have been discovered at Laukunlampi at several locations within the noritic-pyroxenitic intrusion including the significant mineralised upper pyroxenite zone in drill hole ENON0028 (as reported in our recent RNS dated 27 March 2023). No high-grade massive sulphides have yet been discovered within the Laukunlampi mafic-ultramafic intrusion. However, intervals with high amounts of sulphide droplets with high nickel and copper tenors based on handheld pXRF measurements have been discovered both close to the southern and northern contacts of the intrusion and by far the highest nickel tenor to date has been observed in drill hole ENON0028. In addition, significant widths of noritic rocks with disseminated sulphides have been intercepted with several drill holes.
