Appendix 2: Summary of Licence Holder comments The Licence Holder was provided with the draft Amendment Notice on 03/08/2018 for review and comment. The Licence Holder responded on 06/08/2018, the following comments were received on the draft Amendment Notice: Condition Summary of Licence Holder comment DWER response
Condition: 1.3.6 – 1.3.9 Table: 1.3.4 "Process water tank with a minimum capacity of 113,000 kilolitres" This was a mistake in the Artemis submission, it should have been litres not kilolitres, ie 113kL (or 113,000L). Sorry for this mistake with the units.
Noted. Amendment made.
Condition: 1.3.6 – 1.3.9 Table: 1.3.4 "Slurry pipeline and return water pipeline installed in V-drain which includes sumps sized to contain up to 12 hours of thickener underflow production" We need to clarify, that the collective total of the v-drains and sumps will contain the 12-hour production (not each individual sump / v-drain). Noted. Text amended to clarify. The new text reads: “Slurry pipeline and return water pipeline installed in V-drain, which includes sumps that have been sized to collectively contain up to 12 hours of thickener underflow production"
Page 7
"The V-drain will include sumps sized to contain up to 24 hours of thickener underflow production"
This should be 12-hour capacity, as we have in Table 1.3.4, for Condition 1.3.7 - 1.3.9
Noted. Text on page 7 amended by changing “24” to “12”.

Should we add ‘freshwater’ to Column 4 of Table 4 to "ANZECC/ARMCANZ 95%  trigger values (mg/L)" ?
Noted. Column 4 amended to include the word “freshwater”
Page 10
We have submitted a Mining Proposal to the DMIRS for the construction/operation of the Gekko plant, this is Reg ID 75362. We have an approved Project Management Plan (PMP) for the construction work, this is Reg ID: PM-093300691. We are preparing the PMP for the operation of the Radio Hill plant (including the Gekko Gold Plant) and this PMP will be submitted soon
Noted. Text amended accordingly. “Mining Proposal ID 75362 for Radio Hill Project Miniing Proposal Revision B approved by the Department of Mines Industry Regulation and Safety (DMIRS) including project management plan PM-093-300691 for the construction work. A project management plan for the operation of radio Hill plant is under preparation for approval by DMIRS.”

Will this new Licence become v6 or remain as v5...the 'Instrument' column has L7922/1989/5
It will remain as V 5. The numbering is updated when the licence is re-assessed.

Table 11, Cat 5 / Dust / Potential receptors: should state that no PECs have been recorded on site, this is what the 'Reasoning' column states. On the Page 15, the discussion of PECs on this risk event is correct, therefore please use this wording for Page 14.
Noted. Text on page 14 amended to state that no PECs have been recorded on site.

We requested the address be changed to "Suite 1, 11 Ventnor Avenue - West Perth, 6005, WA" via emails between Michael Williams (Artemis) and Shelley Bee (DWER) in Feb 2018, could we please correct this... the address was instead changed to a Sydney address, therefore - could we amend this to our West Perth address? Our correct address is on the front page of your DWER letter.
