另一方面，克里夫自然资源在运营和活动方面可以被认为是多元化的。 Cliffs Natural Resource是一家全球性自然资源和采矿公司。它是众所周知的500指数S和P成员之一，也因其主要生产铁矿石以及重要的低挥发冶金煤生产商而闻名（Gilberto，2008）。众所周知，Cliff的战略是通过创建一个专注于服务于增长最快和最大的钢铁市场的焦点，不断实现采矿业更高的多样化和规模。已知该组织的驱动因素是其在资本，环境和社会管理方面的核心价值。该组织与全球努力在利益相关者面前提供财务和业务透明度相关（Takakuwa，2011）。基于此，可以说组织在竞争优势方面多样化，而不是多元化组织的基本运作。
因此，可以说南方铜业的组织在多元化方面超过了Cliffs Natural Resources公司。
On the other hand, Cliff Natural Resources can be considered diversified in terms of its operations and activities. Cliffs Natural Resource is a global natural resources and mining company. It is known to be a member of the 500 Index S and P and is also well known for its major production of iron ore along with a significant producer of low as well as high volatile metallurgical coal (Gilberto, 2008). The strategy of Cliff is known to be continuously achieving a higher diversification and scale in the industry of mining by the creation of a focus to serve the fastest growing and largest markets of steel. The driving factor of the organization is known to be its core values with respect to stewardship of the capital, environment and the society. The organization is in association with the globe endeavour for providing transparency in finance and operations in front of the stakeholders (Takakuwa, 2011). Based on this, it can be stated that the organization diversifies in terms of competitive advantages rather than diversifying the basic operations of the organization.
Hence, it can be stated that the organization of Southern Copper outshines the corporation of Cliffs Natural Resources in terms of diversification.
The Corporation of Southern Copper is known to be instituting extensive programs on environmental conversation at the facilities of mining in Mexico and Peru. The environmental policy of the organization consists of a number of different environmental programs (Eurek, 2010). These include systems for the recovery of water for the conservation of water and for minimizing the effect over streams nearby, programs of reforestation for the stabilization of the surface over the dams of tailings and implementing the technology of scrubbing within the mines for the reduction of dust being emitted. In the years of 2009, 2010, and 2011, the following capital expenditures had been made for the purpose of environment.
