As expected, the coefficient on PREFILE was negative and significant in both models.
Examining variables with significant coefficients from the polynomial hazard regression model we obtain ratios of 4.78 for BUDGET, 2.15 for PREFILE, and 1.83 for APPOINT relative to AROR.
"The suspension order is temporary until BNMI is able to implement systematic mining and clean-up and relocation of ore prefiles
