Lombok, September 16th 2023 – PT Sumbawa Timur Mining (STM), owner of the Hu’u Project 7th generation Contract of Work (CoW) in Dompu Regency, West Nusa Tenggara is holding a series of seminars and mini workshops in the cities of Mataram, Makassar and Yogyakarta. This event is targeting students from Dompu Regency who are pursuing higher education in the cities. The aim of this activity is to provide students with broader insight about various opportunities and career choices after they graduate from college.

“This activity is facilitated by the Persolkelly Human Resources (HR) development agency. The facilitators help develop students’ soft skills as preparations for entering the business world or the world of work,” said PT STM Principal Communication, Cindy Elza, on Saturday (9/16).

In addition to providing career insight, the company will also use this event to disseminate information regarding the Hu’u Project. This will provide students with a deeper understanding of various aspects of the Hu’u Project, which is still in the exploration phase.

This activity was first held in Mataram City on Saturday, September 16 2023. Similar activities will be held in Makassar City on October 5 2023, and Yogyakarta in November 2023. 

In Mataram, the seminar and mini workshop ‘Yang Muda Yang Siap Kerja’ (Young People Ready to Work) takes place at the Aston Inn Hotel , where 50 students from Dompu take part in this activity.

Cindy explained that this socialization was a form of disclosure of company information.

“We want students to get the right information regarding the Hu’u Project. The information provided includes a general overview of exploration and various aspects and their impact on society, including aspects of employment, environmental management, business opportunities and community development,” he said.

According to her, these students will soon enter the competitive labor market. There are also those who want to return to their hometown and are very interested in joining STM.

“However, as an educated group, students need to understand that the ratio between the availability of job opportunities and the number of job seekers is not always balanced. We hope that after returning from this activity, students will have increased insight into the various career options they can choose after graduating from college, as well as how to achieve them. “In this way, they will be better prepared to compete and develop their abilities in whatever industry they are interested in,” she said.

The expert from Persolkelly, Christina Nangoi, added that this provision begins by helping participants understand their goals and career choices that can be taken based on their respective interests and abilities.

Some of the company’s energy efficiency initiatives have reduced carbon gas emissions

Sumbawa, May 2023: PT Sumbawa Timur Mining (STM), the owner of Contract of Work of the Hu’u Project in Dompu Regency, West Nusa Tenggara Province, Indonesia, is implementing energy efficiency management as part of its commitment to sustainable mining practices. PT STM recognizes the importance of environmental management and monitoring efforts to maintain a balanced ecosystem around the exploration area.

President Director of PT STM, Bede Evans said that any development, for whatever purpose, will potentially have impacts on the environment. PT STM is therefore committed to ensuring that work at the Hu’u Project is carried out to high environmental standards. 

“We see ourselves as part of the community and as contributors to progress and prosperity. Our consistent efforts to protect the environment around our exploration areas demonstrate the high priority we place on responsible and sustainable mining practices,” said Bede Evans.

Among the energy efficiency management strategies that PT STM has implemented include the use of solar panels for supplementary power sources and replacement of lamp types for lighting efficiency. In its energy efficiency efforts, the company noted that PT STM’s use of solar panels has reduced carbon emissions by 75 tons of CO2eq.

Evans said that although PT STM’s activities at the moment are still limited to exploration and mining activities, the company’s energy efficiency efforts have been implemented.

Water Management and Air Quality

Meanwhile, to maintain surface water quality, PT STM has taken various measures including strict monitoring of water usage. Every three months, various tests are conducted at 38 separate surface water, groundwater and seawater locations to determine the water quality at these test points.  Water quality monitoring, testing and analysis are conducted by independent and accredited laboratories. 

PT STM also runs a Waste Water Treatment Plant (WWTP) and the fuel storage site, effluent storage site, and generator site are protected by impermeable barriers to safeguard the surrounding areas from contamination. While these measures are in line with a comprehensive approach to maintaining water quality, a long-term assessment of the Hu’u Project’s water vulnerability was also conducted and this will inform the development of a more in-depth clean water support program.

In terms of air quality management and monitoring, PT STM has undertaken several measures such as irrigating the helipad area, routinely maintaining emissions from operational equipment and vehicles, and undertaking necessary dust abatement measures. PT STM also regularly monitors and measures the concentration of air pollutants such as heavy metals and particulate matter generated by exploration activities to maintain air quality in accordance with recognized environmental standards.

The native flora and fauna of the Hu’u Project are also important for their benefits to the local community. To ensure minimal impacts of mining activities on flora and fauna, PT STM has a rigorous program to mitigate the impacts of land clearing and reclamation by preserving topsoil during these activities and using the preserved topsoil as part of the revegetation process. The success of soil rehabilitation and revegetation is constantly monitored, including the use of surveillance cameras within rehabilitation areas to ensure activities do not impact animal life in the project area.

Evans said, “As we plan to develop the Hu’u Project into a world-class copper mine, we recognize the need to apply strict environmental measures and standards in all that we do.  This includes applying best practices and doing the things we should be doing, even if they are not required by law. We are grateful that our efforts to protect the environment at the Hu’u Project have been recognized by relevant agencies such as the West Nusa Tenggara Energy and Mineral Resources Agency, the Dompu Environmental Agency, and the Bima Environmental Agency.”

The companies in question include PT Abdi Karya Usaha Raya (AKUR), STM Vale Hu’u – Vale Global Group (STM VH VGG), PT Main Cone Vale Global, PT Vale GG, and PT SVH – VGG.

“We remind the public that the mentioned companies have no direct or indirect affiliations with the Hu’u Project, STM, or Vale,” stated Cindy Elza, Principal Communication of STM.

The management of STM also affirms that STM is the sole holder of a Contract of Work legally recognized by the Government (both Central and Regional) to exclusively carry out the development of the Hu’u Project.

“We urge the public not to easily believe in any form of investment offers related to the Hu’u Project that do not originate from official sources of STM. Be sure to verify any offers, either by contacting STM or through other means,” Cindy informed.

Therefore, Cindy noted that STM provides a helpline for the public who wish to confirm or report fraudulent activities misrepresenting STM and Vale, through the email address infoSTM1@vale.com or by contacting the STM Community Relations Team in Project Hu’u Staging at Hu’u District.

In conclusion, Cindy added that “STM will not hesitate to use all available legal measures under applicable laws to protect the legal interests of STM against any individuals, companies, or entities intentionally and unlawfully creating an impression among the general public that their business activities are related or associated with the development activities of the Hu’u Project, which is currently legally conducted by STM and its parent company (Vale).

Didit Susiyanto stated that the handover of the clean water well facility is a manifestation of STM’s commitment to growing and developing alongside the community through its empowerment programs.

“We hope that the clean water well facilities can address the issue of clean water access for the residents of Marada Village. Now, water is readily available, and the infrastructure is in place. In the past, people might have had to travel quite a distance to collect water, but now it is distributed to their homes,” he said. 

He expressed hope that through the construction of these clean water facilities, the community can show their support for the presence of STM, enabling the company to further empower the local residents and utilize the shared potential.

Meanwhile, Hu’u District Head Muhammad Iswan, SKM welcomed the handover of clean water facilities to the residents of Marada Village and stated that STM has made a significant contribution to the empowerment and development of Hu’u in various areas.

“PT STM’s contribution to health, education, empowerment, and public facilities has been quite a lot done by PT STM. Likewise in the field of agriculture with environmentally friendly plants (organic plants). I even participated in the harvest together in Daha yesterday,” he said.

Head of Marada Village, Abdullah Idris, on the other hand, expressed his gratitude and thanks because STM’s assistance has made clean water accessible to the residents. The water is now directly distributed to each household, which is a form of care by the company after witnessing the difficulties the Marada residents faced with clean water following the damage to the water source pipes during the floods in early 2021.

He also urged the residents to continue supporting STM so that it can continue its activities and empowerment programs. “In Marada, there is no more water scarcity. This is extraordinary. Unlike before, where one water tank was shared by the entire village,” he said.

The clean water provided by STM is managed by the Marada Village government through an institution established by the village government. The water is directly supplied to the residents’ homes and is equipped with water meters. Residents are charged Rp. 20,000 per household (KK) for maintenance and incentives for the staff. This cost is much lower than when based on water consumption.

Content Significant Copper and Small Amount of Gold

Jakarta, 21 April 2022 – PT Sumbawa Timur Mining (STM) announced today a newly concluded mineral resource estimate of the Onto copper-gold deposit in Nusa Tenggara Barat Province. The mineral resource estimate, which was completed in December 2021, reported a total 2.1 billion tonnes (Bt) with each ton containing 0.86% of copper and 0.48 gram of gold. Details of these updated mineral resources estimated as follows: total Indicated mineral resource of 1.1 billion tonnes (Bt) @ 0.96% Cu and 0.58 g/t Au and a total Inferred mineral resource of approximately 1.0 Bt @ 0.7% Cu and 0.4 g/t Au.

The first public announcement of the Onto Deposit mineral resource estimate in December 2019 reported a total Inferred mineral resource of 0.76 Bt @ 0.93% Cu and 0.56 g/t Au and a total Inferred mineral resource of 0.96 Bt @ 0.87% Cu and 0.44 g/t Au. This represents an increase in the size of the Onto deposit of 0.4 Bt or equivalent to >20% since the announcement of the first resource estimate.

The Onto deposit is part of STM’s Hu’u Project, which is a 7th generation Contract of Work (CoW) entered into with the Government of Indonesia on 19 February 1998 located in Dompu and Bima Regencies in Nusa Tenggara Barat. STM is majority owned (80%) by Vale S.A., through Eastern Star Resources Pty Ltd, and Antam Tbk (20%).

Bede Evans, President Director of STM said, “This latest mineral resource estimate strengthener view that the Onto deposit has the potential to be developed into a world-class copper mining operation. The increase in the Onto mineral resource by 0.4 Bt is the result of the effort, support and commitment of the Hu’u Project team over the last two years. This provides the STM shareholders and the STM team with cautious optimism as we enter into more advanced stages of project development .”

STM has conducted exploration activities within the Hu’u Project CoW since 2010. The mineral resource estimate is based on 74 holes, with a total length of 74,130 meters, drilled into the Onto deposit. Drilling will continue in 2022 and beyond to support studies to further define the size, extent and characteristics of the mineral resource and provide input to engineering studies. In total, STM has completed 108 drill holes (115,591 meters) within the CoW (at Onto and other prospects) since exploration began in 2010.

Mr Evans continued, “Whilst we are very pleased to report an increase of the Onto deposit mineral resource, much work remains to be undertaken to assess technical, environmental, social and financial factors as part of our ongoing feasibility studies. Ultimately, it is our hope that these feasibility studies will define a technically and economically viable mining operation for STM to take into further development.”

Hashari Kamaruddin, Director of STM, reaffirmed his confidence in the Hu’u Project, “I am very pleased with the progress of the Hu’u Project and the new mineral resource statement announced today. The strong collaborative relationship between the STM shareholders and the solid support from the Government of Indonesia and Government of West Nusa Tenggara Province gives us confidence that the Hu’u Project has the potential to be a significant mining operation in Indonesia.”

STM is currently undertaking feasibility studies aimed at further mineral resource definition and to assess hydrogeological, geothermal, and geotechnical characteristics of the deposit. Several technical challenges need to be overcome as part of the feasibility studies in order to confirm that the Onto deposit and Hu’u Project can be developed into a world-class underground mining operation.

The significance of the Onto deposit and Hu’u Project to the mining industry in Indonesia was recently reflected with STM being awarded Best Exploration Expenditure, Best Discovery and Best in Class by the Association of Indonesian Geologists (IAGI) during their IAGI Awards 2020. STM Director of Operations, Mr James Connolly, emphasized the significance of the three IAGI Awards: “It’s a proud moment for the STM team and the shareholders to be awarded such prestigious accolades. We thank IAGI for this recognition and thank the STM team, past and present, who contributed to the Onto deposit discovery and the operation of the Hu’u Project.”

STM also confirmed that site operations have recommenced following a temporary suspension of operations due the coronavirus pandemic. As Bede Evans stated, “We undertook a number of measures in March and April 2020 to temporarily slow down our operations. Through our close working relationship with the Dompu Regency government, we are remobilizing our staff and contractors to the Hu’u Project site.”
