91.5m @ 50.6% mass recovery to a 69.2% Fe concentrate in hole MGD019 from 90.5m
118m @ 43.2% mass recovery to a 67.5% Fe concentrate in hole MGD018 from 76m
188 m @ 45.7% mass recovery to a 67.6% Fe concentrate in hole MGD021 from 113m
128m @ 42.5% mass recovery to a 68.5% Fe concentrate in hole MGRD072 from 146m
These results show greater thickness than at the northern parts of the project
The mass recovery of magnetite is exceptional

What the testwork
shows
Both low sulphur coarse and fine grained variants produced high quality magnetite concentrate within the specifications for Blast Furnace pellet feed.
The coarse grained low sulphur variant, which is a dominant type
at Magnetite Range has excellent mass recovery to concentrate.
Pre-concentration by coarse cobbing was effective, rejecting significant amounts of impurities and reducing the mass required for milling.
Fine grained magnetite BIF: 80 per cent passing size (P80) = 45 micronsCoarse grained magnetite BIF: P80 = 75 micronsThis is a competitive advantage, potentially reducing the grinding energy requirements.

Pre-concentration route favoured
Dry cobbing pre-concentration route
•Reduces water consumption•Improves milling efficiency•Early rejection of contaminants ahead of milling
The mass recovery of magnetite is higher than for many other local projects (>40%)

Investors should be aware that should forward looking statements or projections become materially incorrect, ACS intends to comply with the ASX continuous disclosure requirements and inform the market of significant changes.
• You should not act and refrain from acting in reliance on this presentation. This presentation is an overview of ACS and does not purport to be all inclusive or to contain all information that the recipients of this presentation may require in order to make an informed assessment concerning ACS’s prospects. You should conduct your own investigations and perform your own analysis in order to satisfy yourself as to the accuracy and completeness of the matters presented in this presentation, or consult your investment adviser before making any investment decision.
* The target is based on a strike extent of the mineralised sequence of 10 kilometres, which is derived from aeromagnetic data and partially confirmed by drilling. Typical widths of between 45 to 60 metres are assumed, which is well represented by the available drilling data. At the time of this presentation 42 core holes and 83 RC holes for approximately 19,000 metres had been drilled. The target considers a tabular horizon with a geometry that dips between 50 and 70 degrees, interpreted from cross sections. The target is stated to a vertical depth of 220 metres. An assumed specific gravity of 3.0 has been applied. The Exploration Target is conceptual in nature only and should not be misconstrued as a Mineral Resource estimate. It should be noted that insufficient Exploration has been conducted to enable the estimation and reporting of a Mineral Resource in accordance with the 2004 edition of the Australasian Code for the reporting of Exploration Results Mineral Resources and Ore Reserves (JORC Code) and this target should be considered in accordance with Clause 18 of the JORC Code as conceptual in nature only and it is uncertain whether on-going Exploration will lead to the delineation of Mineral Resources or Ore Reserves
• The information in this presentation that relates to exploration results, mineral resources or ore reserves has been compiled by Mr Terence Butler-Blaxell MAust IMM who is a director of Accent Resources NL. Mr Butler-Blaxell has sufficient experience that is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he has undertaken to qualify as a competent person as defined in the 2004 edition of the Australasian Code for the reporting of exploration results, mineral resources and ore reserves. Mr Butler-Blaxell consents to the inclusion in this report of the matters based on his information in the form and context in which it appears.
