Legend Mining Limited Reports the Results of the Next Nine Diamond Drill Holes (RKDD045-RKDD053) At the Mawson Nickel-Copper-Cobalt Prospect Within the Rockford Project, Fraser Range, Western Australia
Legend Mining Limited reported the results of the next nine diamond drill holes (RKDD045-RKDD053) at the Mawson nickel-copper-cobalt prospect within the Rockford project, Fraser Range, Western Australia. A total of nine further diamond drill holes have been completed (RKDD045 - RKDD053), with two rigs continuing double-shift diamond drilling. RKDD053 was designed to test an offhole conductor from RKDD043, whilst holes RKDD045 - RKDD052 continued the systematic step-out diamond drilling across Mawson, adding critical data to existing datasets. This step-out drilling continues to define mineralized intrusion and importantly, the architecture of the Mawson intrusion. The 3D model driving predictive exploration at Mawson continues to evolve with additional data and continues to be very accurate. This bodes well for continued selection of targets to test for the preferred host lithologies and structurally favorable positions to host massive Ni-Cu mineralization across the Mawson intrusion. Section 6,598,400mN - Diamond drill holes RKDD041/050/053 have been completed on section 6,598,400mN. Drilling was designed to follow the mineralized intrusion to the west and east of RKDD043, while RKDD053 was designed to test the offhole conductor above RKDD043, interpreted to be extensions of the massive and semi-massive Ni-Cu sulphide mineralization encountered in-hole. RKDD053 intersected a zone of dominantly massive, semi-massive, and matrix sulphide, with lesser heavy disseminated and disseminated sulphide between 132.07m and 163.28m before finishing at 260.4m in meta-BIF. DHTEM is scheduled on RKDD053 to search for further extensions to the mineralization. RKDD050 drilled 200m west of RKDD043 intersected mineralized intrusion including narrow zones of semi-massive veins and net-texture sulphide within broader zones of disseminated mineralization from 94.1m to 221.6m downhole. RKDD041 drilled 200m east of RKDD043 was initially drilled to 300m before being re-entered and extended to 486.4m. The drill hole intersected a thickened package of metasediments and meta-BIF's, interpreted to be a structural control resulting in a change in direction of the mineralized intrusion from NE-SW to NNW-SSE. The current interpretation is RKDD043/053 is a junction point whereby the western chonolith and eastern chonolith join. The change in orientation of the intrusion potentially explains the massive sulphide mineralization encountered in RKDD043 and RKDD053, whereby a natural structural trap is created as a result of a change in orientation due to the structural control. DHTEM is scheduled to be completed on RKDD050 and RKDD041. Section 6,598,200mN - Diamond drill holes RKDD045/047/048/052 have been completed on section 6,598,200mN. Drilling targeted the interpreted southern extension of the eastern chonolith. All holes hit extensive packages of metasediments and meta-BIF's, marking the southern closure of the Mawson intrusion. Section 6,599,200mN - Diamond drill holes RKDD046/049/051 have been completed on section 6,599,200mN, west of RKDD044. Drilling targeted the interpreted northern extension of the eastern chonolith. As reported on 28 April 2021, RKDD044 intersected a heavily mineralized gabbronorite to 476.75m, including a zone of net-textured, semi-massive, and massive Ni-Cu sulphide from 453.2m to 458.1m. Drill holes RKDD046, RKDD049 and RKDD051 encountered extensive mineralized mafic and ultramafic intrusion. Mineralization intersected included disseminated, blebby, heavy disseminated, matrix, and semi-massive magmatic Ni-Cu sulphide. RKDD049 intersected a 46m zone of sulphide mineralization from 402.8m to 448.8m downhole including semi-massive and matrix sulphide between 440m to 441.9m and 447.9m to 448.8m. The mineralized intrusion remains open to the west, east and north. Further expansion drilling is planned to follow the mineralized intrusion in the open directions.
DHTEM completed on RKDD042 and RKDD044 identified a large offhole conductor of significant size and thickness adjacent to the interpreted MLTEM stratigraphic conductor D3. Drill holes have been designed and will be completed east of RKDD044 to better constrain this conductor before drill testing. Ongoing drilling across Mawson will focus on continued definition of these intrusive bodies and targeting of structural trap sites for massive Ni-Cu sulphide accumulation. Assay results from drill holes RKDD035-RKDD042 have now been received, returning intervals of low-grade Ni-Cu values in the range 0.05-0.2% Ni associated with disseminated sulphide in mafic/ultramafic intrusive, as expected. Results from drill holes RKDD043 and RKDD044, which intersected significant Ni-Cu sulphide intervals are expected within the next 2-3 weeks. Mawson Future Programmes - Diamond drilling continuing with two diamond rigs at Mawson systematically testing across priority areas. Ongoing DHTEM on all completed diamond drill holes to assist follow up drilling. Integration of DD, RC, aircore geochemical and geophysical datasets to evolve 3D emplacement model of Mawson, with new constrained gravity and magnetic inversions ongoing.
