[Lower confidence: the company's own IR site (trekmetals.com.au) returned HTTP 429 on every attempt this session; cross-checked via marketscreener.com and simplywall.st rather than a direct IR-page load. Note: secondary sources also indicate the underlying ASX ticker changed from ZRL to TKM in Jan 2017 and disagree on the rest of the current management/board roster -- only this one high-confidence role is written here; the rest is deliberately omitted pending direct verification.]
