Assays received for the first 12 holes of maiden drill program at Andover
South - Initial drilling concentrated in centre of tenement E47/4062 in
Target Area 1 and 2 – Refer Appendix Table 1 and Table 2

Within the next week remaining holes sampled from Target Area 1 & 2,
as well as samples from holes drilled at Target Area 7, will be dispatched
to the laboratory for assaying – results expected 3-4 weeks thereafter

This possibly answers your query. I'm guessing hole 23 was referenced without assays due to it being a significant find. I'm sure the rest will come in due course. Or maybe they're all dusters and they're trying hide them from the market. Whatever floats your boat I guess.
