澳洲上市公司Critical Resources在新西兰Lammerlaw金矿项目的Stony Creek目标区内发现了一系列砷-锑-钨土壤异常[1]。该公司采集了143个土壤样本，沿5.4公里横贯线布置，在约3.2公里区间内检测到多个砷-锑-钨病指元素异常，其中砷最高达238 ppm、锑达25 ppm，且10个样本中砷含量至少达到30 ppm[1]。这些发现进一步支持了该区域存在造山型金系统的地质假设[1]。
Critical Resources董事长Tim Wither表示，"土壤地球化学是将410平方公里许可证范围缩小至值得钻探地块的最快速和最低成本工具"[1]。该公司通过系统的低成本地球化学勘探，成功将搜索范围从Lammerlaw的410平方公里缩小到数个高优先级目标，为后续钻探测试做准备[1]。此前，位于Stony Creek东13公里的Devils Creek目标曾返回5.42克/吨黄金的芯样品位[1]。Critical Resources在新西兰拥有1,694平方公里的勘探组合[1]。
Australian-listed Critical Resources has identified a series of arsenic-antimony-tungsten soil anomalies within the Stony Creek target area of its Lammerlaw gold project in New Zealand, providing further geological support for an orogenic gold system in the region.[1] The company conducted a systematic low-cost geochemical exploration program that successfully narrowed the search scope from 410 square kilometers to several high-priority targets in preparation for subsequent drilling tests.[1]
The survey collected 143 soil samples distributed along a 5.4-kilometer traverse line, detecting multiple pathfinder element anomalies across approximately 3.2 kilometers.[1] Peak results yielded arsenic readings of 238 parts per million and antimony at 25 parts per million, with 10 samples containing arsenic concentrations of at least 30 parts per million.[1] The Devils Creek target, located 13 kilometers east of Stony Creek, previously returned a core sample grade of 5.42 grams per tonne of gold, demonstrating the prospectivity of the broader area.[1]
Critical Resources holds an exploration portfolio covering 1,694 square kilometers across New Zealand.[1] Tim Wither, the company's chairman, stated that "soil geochemistry is the fastest and lowest-cost tool to narrow the 410 square kilometre license area down to drill-worthy ground."[1]
