Section 1.Conflict Minerals disclosure

​

Item 1.01 Conflict Minerals Disclosure

​

Conflict Minerals Disclosure

​

An indirect subsidiary of Alliance Resource Partners, L.P. ('we,' 'our' or 'ARLP'), Matrix Design Group, LLC ('Matrix'), provides a variety of mine products and services for ARLP's mining operations and to unrelated third-parties. These mine products, like virtually all consumer electronics, contain various metals, including tantalum, tin, tungsten and gold ('Conflict Minerals'), which originate from mines around the world.

​

Pursuant to the Securities and Exchange Commission Final Rule on Conflict Minerals, 17 CFR Parts 240 and 249b (the 'SEC Final Rule'), we have performed a reasonable country of origin inquiry regarding Conflict Minerals from applicable suppliers using the template designed by the Responsible Minerals Initiative ('RMI'). Matrix designs its products but is several layers removed from the purchase by Matrix's suppliers of the materials used to contract manufacture the Matrix products as well as the actual mining of minerals that may be used in the Matrix products. Consequently, Matrix's procedures include communicating to its suppliers the importance of compliance with the SEC Final Rule. Because Matrix lacks direct access to sub-tier suppliers, we relied on Matrix's contract manufacturers to provide information on the origin of the Conflict Minerals contained in any products supplied to Matrix using the RMI template. We received responses from 100% of requested supply-chain surveys from Matrix's contract manufacturers but the information provided in those responses was not complete regarding the source of all Conflict Minerals that may have been contained in the products they manufactured for Matrix. Among other things, these contract manufacturers buy materials from many different suppliers to produce products for many different customers and are not able to determine which set of Conflict Minerals may have been used to produce such products for Matrix versus others of their customers. Nevertheless, we reviewed the supply-chain surveys against the list of smelter facilities which have been identified as 'conflict free' by the RMI and the Responsible Minerals Assurance Process and performed independent searches for information on the smelter facilities included in each supply-chain survey. Several hundred smelters were identified in the responses and it appears that three are located in the DRC or adjoining countries.

​

Our inquiry into the sources and chain of custody of any Conflict Minerals in our products did not, as of now, provide us enough information to determine whether the Conflict Minerals used by Matrix in its products actually originated in the Democratic Republic of the Congo or adjoining countries, or whether they came from recycled or scrap sources, or whether they directly or indirectly financed or benefited armed groups for the year ended December 31, 2020.
