Further details:
Delta holds a Mining Licence over Mt Ida. As per the March 2023 quarterly, they have now submitted their Mining Proposal and Mine Closure Plan. The target turnaround time on this consent is fairly short, but its a starting and stopping clock so each time more information is sought, the time clock stops. Delta expects this during 2023.

The level of Delta drilling is absolutely huge. In the March 2023 quarter Delta drilled 36,332m at Mt Ida and 18,560m at Yinnetharra. Those totals are correctly stated as being for a quarter, not for a year. Delta has 5 rigs at Mt Ida. Yinnetharra had two rigs operating for most of Q1 and had a 3rd arrive mid-March.

Delta's announcement of 13 April 2023 noted that at Mt Ida there was a further 60,000m across more than 200 holes planned over the remainder of 2023. Delta is also planning to drill 90,000m at Yinnetharra across more than 400 holes in 2023 and most of that is by September. The 14 April announcement noted the project was at 101 holes for 21,150m and was on track for 230 further holes by September. Around 70,000m is planned at Yinnetharra over the remainder of the year and this includes drilling 230 holes by September requires over one hole per day (on average). The March 2023 quarterly noted more than 6,133 Mt Ida samples at the lab and 4,322 Yinnetharra samples at the lab so Delta had over 10,000 assay's outstanding. This drilling program is huge.

While only a limited number of Yinnetharra drill results have come back, the drilling is increasingly consistent with looking to define a resource rather than a lot of exploratory drilling. The drill map for M1 below is a good example of that.
