The shares sold were from a family trust. Tonkin was a beneficiary. Perhaps one of the other beneficiaries needed funds. Still needs an explanation givens that the market does not respond well to directors disposing shares.
I believe the slow response by SLR to the gold price recovery is due to margin calls. Note RED, which is not allowed purchase on margin by ComSec is responding well. SLR allowed 80%
