Dateline Resources drilling has reeled in two giant hits going 1g/t gold, including a richer zone of 10.7m of 8.17g/t, as it works to bring its Colosseum project in California back into production. The company says its first two diamond drillholes show 203.6m grading 1.03g/t gold and 192m running at 1g/t, confirming the potential for expanded mineralisation at the site.
