Kaiser Reef (ASX:KAU) said infill soil sampling confirmed strong, neighboring gold-arsenic anomalism along multiple structures over the full 4.4 kilometers of strike at the Maldon gold project in Queensland, according to a Tuesday Australian bourse filing.

Infill sampling covers an area of 2.7 kilometers-squared of prospective ground to the north of Maldon. The survey resulted in a peak soil result of 2.7 grams-per-tonne grade of gold and four further samples at around 1 gram-per-tonne grade of gold. The anomalism extends up to 1.5 kilometers and four distinct anomalous north-south trends were delineated.

The company's shares jumped nearly 3% in recent trading on Tuesday.
