Arch Coal plans to invest $3.0 million in ADA to fund near-term growth opportunities. ADA has been successful at developing technologies that improve the performance of coals from Wyoming’s Powder River Basin (PRB). In addition to flue gas conditioning chemicals used to aid in the collection of ash from PRB coals, it also developed a cost-effective brominated activated carbon technology that provides a means of achieving 90% removal of mercury emissions from PRB coals and CyClean technology, a proprietary coal additive that improves combustion of PRB coals in cyclone boilers resulting in enhanced efficiency and reduced emissions of mercury and nitrogen oxides. For the past several years, ADA has worked with Arch to explore certain unique characteristics of some of its coals that allow them to be burned with lower mercury emissions.The first step of the investment was completed on March 23 with the purchase of 143,885 shares of ADA for $1.0 million. The remaining $2.0 million is consideration for an exclusive license to use ADA’s technology to provide environmental benefits for coals mined by Arch that are used to produce electricity. The license is currently being negotiated to define the royalty structure and is expected to be finalized in the next month. Arch has been a significant shareholder of ADA since 2003 when the Company spun-out as a separate public entity.Mike Durham, ADA President and CEO, stated, “This investment will continue our long-standing relationship with Arch and allow the company to fund opportunities that have the potential for significant near-term increases in revenues and earnings such as CyClean. As Congress is considering a year extension to the Section 45 tax credits, we want to be in a position to respond quickly to sell and install additional CyClean systems to produce refined coal.”ADA-ES is a leader in clean coal technology and the associated specialty chemicals. It develops and implements proprietary environmental technology and specialty chemicals that enable coal-fuelled power plants to enhance existing air pollution control equipment, maximise capacity and improve operating efficiencies. ADA-ES supplies activated carbon (AC) injection systems, mercury measurement instrumentation, and related services. Through Clean Coal Solutions, the company provides its patented refined coal technology, CyClean, to utilities to enhance combustion of and reduce emissions from PRB coals in cyclone boilers, which qualifies for Section 45 tax credits. In addition, to meet the needs of the power industry for mercury control, a joint venture of the company, ADA Carbon Solutions, is developing state-of-the-art facilities to produce AC with the first plant projected to come on-line in 2010. The company is also developing technologies for power plants to address issues related to the emissions of carbon dioxide.
The 2018 International Tin Conference in Budapest was successfully held last month, with over 200 delegates in attendance. The conference programme highlighted, in particular, the increasing focus on responsible tin sourcing, while assessing the outlook for tin supply and impact of new technologies.During the conference, various views on responsible sourcing were expressed by a range of stakeholders across the tin supply chain. Supply chain due diligence emerged as a key theme, with the London Metal Exchange, European Commission, the International Tin Association (ITA) all outlining progress in developing and implementing new supply-chain standards and requirements for tin. Tin consumers present raised concerns about overlapping or unharmonized standards. Tin producers hope that the ITA Code of Conduct can address this concern by becoming the universal standard for responsible tin supply in the tin industry.The growth of Electric Vehicles presents new opportunities for tin, with various potential uses in lithium-ion batteries and in the development of supporting infrastructure. However, innovation in the tin industry is also visible in mining and processing technology. Presentations outlined how optical ore sorting can successfully be applied to tin ore processing for hard-rock mines and that it has been adopted both by the San Rafael mine in Peru and Renison in Tasmania.A number of tin exploration and development companies provided progress updates for projects in Australia, Canada, DR Congo and Morocco. Some existing producers outlined how they are working on new sources of tin supply, with Minsur developing its B2 tailings project and carrying out advanced exploration at a number of deposits proximal to the San Rafael mine. PT Timah is trialling both onshore and offshore borehole mining with plans to invest in this extraction method in the coming years. However, the ITA continues to warn that global tin supply will likely be insufficient to meet rising demand in the years ahead without price increases.Its next event will be Asia Tin Week in Shenzhen, China, to be held provisionally September 16-18, 2018.
