浅谈资源估算在境外矿业项目投标决策中的重要作用

摘要

With the example of a copper mine abroad and by means of the geologic modeling and resources estimate in respect with the deposit,it’s found out that resources and metals in the deposit show a negative variation in contrast with that shown in international tender document.Based on the tech-economic evaluation conducted,Chinese companies which intend to participate in the bidding resolutely determine to withdraw themselves from the proj ect bidding and thus avoiding losses on investment.Therefore,it shows that cost estimate plays an important role in investment and decision-making of mining proj ects.%以国外某铜矿为例，通过对矿床进行地质建模和资源估算，发现与国际招标文件相比，矿床资源量、金属量有很大程度的负变。在进行技术经济评价的基础上，参与投标的国内公司果断决策，选择退出项目招标，避免了投资损失，从而说明在矿业项目投资及决策方面，资源估算具有非常重要的作用。
