The QB2 project is one of the world’s largest undeveloped copper resources. QB2 is expected to have low operating costs, an initial mine life of 28 years and significant potential for further growth.

2019年3月29日，我们完成了一项交易，SMM/SC认购了QBSA 30%的间接权益，QBSA拥有QB2铜矿开发项目。在交易结束时，SMM/SC向QBSA提供了13亿美元（9.66亿美元），在2019年剩余时间内还提供了4.44亿美元（3.36亿美元），其中3800万美元用于支付2019年贷款预付款的利息。

In the fourth quarter of 2019, we closed the US$2.5 billion limited recourse project financing to fund the development of QB2. With funding from the project financing and the partnering transaction with SMM/SC, our first contributions to the project are not expected until early 2021

The project is comprised of a mine area with a concentrator plant and tailings facility, utilities and port facilities.

表生矿体（近地表矿床）是在Quebrada Blanca的初始阶段开采的。QB2将在现有作业的基础上开发更深层的硫化物资源。因此，QB2被有效地预剥离，大大降低了项目成本。

• Initial 28-year mine life will use only 25% of total reserves and resources
• Maximum pit depth of 720 meters

Concentrator

铜矿石的加工，包括破碎、选矿、散装浮选、浓缩和过滤，将在一个新的选矿厂进行，该厂的生产能力为14万吨/天。

Tailings Facility

Mine tailings will be transported from the concentrator plant to the tailings facility. The facility will be built to industry-leading standards for safety and security to ensure safe management and storage.

公用事业

公用事业constructed to service QB2 will include the concentrate and desalinated water transport systems, high-voltage power lines and access roads.

Port Facilities and Desalination Plant

QB2将包括在智利塔拉帕卡地区的采矿作业中首次大规模使用淡化海水，以代替淡水使用。此外，还将建造港口设施，将矿物浓缩物装上船只运往市场。
