So, I e-mailed them. This is their reply: "The paler tone of yellow on the indicative schedule represents the prep (land access, statutory approvals, drill design) and post drilling activities (core/sample processing, waiting on assays, QAQC, reporting)." I think they left out a couple of words, but safe to say it indicates progress. Hope that helps.
