Slide 11: Carr Boyd Nickel Project - Overview
Carr Boyd Nickel Project - Overview ❑ Carr Boyd Nickel Deposit first discovered in 1968, over 3,000 NiT and 1,000 CuT mined 1972, non-JORC remnant resource For personal use only ❑ Estrella acquired 3 ML’s and 6 EL’s in 2018 encompassing the entire Carr Boyd Igneous Complex and made the T5 discovery
Slide 12: Understanding Geological Context to Minimise Exploration Risk
Understanding Geological Context to Minimise Exploration Risk Estrella embarked upon a “back-to-basics” strategy to contextualise the Carr Boyd Intrusion in both time and space, employing both scientific study and new technology, to minimise exploration risk and to define the most suitable For perso
Slide 13: Why Go Back to Basics?
Why Go Back to Basics? ❑ Last detailed scientific study on Carr Boyd was in 1972, Carr Boyd has not been understood in regional or local context ❑ Variations on the layered intrusive model used for exploration were largely unsuccessful for 50 years For personal use only ❑ Active interest in nickel s
Slide 14: Carr Boyd Intrusive Complex - What does back-to-basics look like
Carr Boyd Intrusive Complex - What does “back-to-basics” look like ❑ We know the system is fertile however…. What age is the intrusion? Exactly which way was down? ❑ Type, complexity and shape of intrusion? What were the flow dynamics and direction? Local or distal sulphur sources? For personal use
Slide 15: Carr Boyd Intrusive Complex – Some of the Answers
Carr Boyd Intrusive Complex – Some of the Answers ❑ CSIRO dated the CBIC at ~2690 ± 50 Ma For personal use only ❑ Just younger than Mt Keith, Kambalda, Scotia - played a part in the early orogenic process ❑ Will show effects of all regional deformation including overturning ❑ Only example of mineral
Slide 16: Paleo-gravity, Inflation, Rotation
Paleo-gravity, Inflation, Rotation ❑ This might be a particularly interesting learning if For personal use only exploring an intrusion that has not undergone much tilting during deformation where the basal contact cannot be observed through mapping ❑ Pyroxenite-Gabbro layering in the upper intrusion
Slide 17: Paleo-gravity, Inflation, Rotation
Paleo-gravity, Inflation, Rotation ❑ Nickel and copper sulphide intercepts can now be For personal use only put in context with respect to the original orientation of the intrusion ❑ Many of the historical intercepts are not on basal contact positions but close enough to indicate T5 sulphides are tr
Slide 18: Carr Boyd - Summary
Carr Boyd - Summary Carr Boyd Exploration Window Quantified and Located in 3D Space with a JORC Exploration Target of between 35,000 NiT and 105,000 NiT For personal use only Clearly defined 16km of basal contact down to 1.5km depth, with an oriented and vectored geological model in ongoing developm
Slide 19: Investment Opportunity
Investment Opportunity For personal use only ❑ Active nickel explorer in a tier-1 mining jurisdiction ❑ Focused on discovery of a World Class, High Quality, Nickel Sulphide Resource ❑ Transitioning to near-term production - cashflows to assist exploration and development ❑ Using up to date knowledge
