LAINEJAUR - BAYROCK'S FLAGSHIP ASSET
- A nickel dominant, massive sulphide resource with considerable upside
- Discovered in the early 1940's by electrical surveying followed by excavation under moraine
- Shallow underground mine (<150meters) operated until 1945
- production of 101kt at an average grade of 2.2% Ni, 0.1% Co and 0.9% Cu
- No modern exploration was undertaken until 2007 when Blackstone Minerals completed 42 core drill holes for 13,200m
- The Lainejaur 2018 Mineral Resource Estimate was restricted to a very small 0.40km2 tenement
- Bayrock has now secured a 41.2km2 holding which enables investigation of potential down- dip extensions as well as nearby untested Ni-Cu targets.

LAINEJAUR MINERAL RESOURCE ESTIMATE
- JORC 2012 compliant Inferred Mineral Resource of 460,000t @ 2.2% Ni, 0.7% Cu, 0.15% Co, 0.68/t Pd, 0.2g/t Pt and 0.65g/t Au (3.4% NiEq)
- The Resource is open down dip and does not include a considerable tonnage of low-grade Ni and Cu
- Drill intersections (within the Resource) include:
- 7.65m @ 2.1% Ni, 0.10% Co and 1.01% Cu from 168m in LAI-07-010
- 5.18m @2.64% Ni, 0.10% Co and 0.06% Cu from 215.9m in LAI-07-14A
- 9.88 @ 2.28% Ni, 0.17% Co and 0.61% from 277.35m in LAI-07-15
Lainejaur is located in the established Skellefteå mining district
LAINEJAUR - RESOURCE EXTENSION POTENTIAL
- The deposit is open down dip and the deepest intersection was 2.85 meters of 1.63% of Ni, 0.51% Cu, 0.19% Co,2.16g/t Pd, 0.62 g/t and 0.83 g/t Au from 558.3m, including 0.7m of 2.89% Ni, 0.13% Co, 8.8g/t Pd, 2.5g/t Pt and 2.9g/t Au
- Mines in the Skelleftea Mining District operate to more than 1500 meters depth
- A considerable tonnage (~1.4Mt) of lower grade Ni-Cu halo mineralisation grading >0.5%NiEq was not included in the 2018 Mineral Resource Estimate
LAINEJAUR - WIDER PROJECT EXPLORATION POTENTIAL
- During 2017 and 2018, Berkut Minerals (now Carnaby Resources) conducted EM and geochemical surveys
- Several new EM anomalies were identified along a 6km arc from the Lainejaur deposit
- These anomalies are priority drill targets for Lainejaur ‘lookalike’ deposits
- A surface veneer of transported glacial sediment, commonly 15-25 thick, covers much of the Lainejaur surrounds and improvements in geophysical application now provide better detection of buried nickel sulphides

Berkut Minerals Limited (now Carnaby Resources Limited) announced the most recent Mineral Resource Estimate for the Lainejaur deposit on 12 February 2018. The information that relates to the 2018 Lainejaur Mineral Resource Estimate was based on information compiled by Mr Paul Payne, an employee of PayneGeo and a Fellow of the AusIMM. The information that relates to exploration and drill results at Lainejaur was provided by Mr Rob Watkins, a Director of Carnaby Resources Limited and a Member of the AusIMM. Both Mr Payne and Mr Watkins have sufficient experience that are relevant to the style of mineralisation and type of deposit under consideration and to the activities which they undertook to each qualify as a Competent Person as defined in the December 2012 edition of the “Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves” (JORC Code).
Nickel Equivalent calculation: The NiEq % calculation for Lainejaur used throughout this website is based on prevailing metals prices as of 15 December 2021 and calculated using the formula NiEq kt = (Ni kt * Ni price + Cu kt * Cu price + Co kt * Co price + Pd oz * Pd price + Pt oz * Pt price + Au oz * Au price) / Ni price, then NiEq kt / Mineral Resource Tonnage.
Other information that relates to the projects have been provided by Dr Ian J. Pringle, Managing Director of Bayrock Resources Limited and a Member of the AusIMM. Dr Pringle has sufficient experience that is relevant to the style of mineralisation and type of deposit under consideration and to the activities which he undertook to qualify as a Competent Person as defined in the December 2012 edition of the “Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves” (JORC Code).
