The latest results from a programme primarily designed to corroborate assay grades from previous RC drilling, and provide geological information and expand the footprint of the mineralised zones, build nicely towards the release of the company's maiden resource estimate later this year.

The hit getting most attention was a 24.7m interval grading 23.35% Zn-equivalent from 143.05m depth. This came from the same area where three RC drill holes intersected the likes of 18.29m at 3.77% Zn-equivalent from 117.35m depth, 6.1m at 22.73% Zn-equivalent from 140.21m depth and 3.05m at 3.86% Zn-equivalent from 117.35m depth.

Nevada Zinc said core holes that actually twinned previous RC holes were "largely similar" to the extent and grade of mineralisation intersected.

"Some areas showed significantly higher grade partly becaue the core drilling equipment, with improved mudding techniques, allowed for better recovery of the mineralised zone than with the RC drilling  equipment," the company said.

CEO Bruce Durham said the first core programme had more than met expectations.

"With the very strong price performance over the last year and with consensus forecasts for sustained or higher zinc prices, Nevada Zinc is well positioned to take advantage of a strong zinc market," he said.

The next step for the company will be the initial 43-101 resource estimate later this year, which Nevada Zinc will hope provides some positive share price momentum.

It's Toronto-listed stock has more than halved in the past year to sit at C$0.21 (US$0.16) per share on March 1.
