Jakarta, Juni 2024: PT Sumbawa Timur Mining (“STM”) again urges the public to remain vigilant against parties claiming affiliation or having a working relationship (whether directly or indirectly) with STM and its shareholders (in this case, Vale and Antam) regarding copper mining exploration activities currently conducted by STM in Dompu Regency, West Nusa Tenggara Province (hereinafter referred to as the “Hu’u Project”).

STM management also emphasizes that STM is the sole legitimate concession holder based

on the Contract of Work related to the development of the Hu’u Project. The implementation of these activities is supervised by the Indonesian Government and is ensured to comply with applicable laws and regulations.

Cindy Elza, STM’s Principal Communication explained that recently they have frequently received complaints and requests for confirmation from the public regarding the project. “Complaints are received through the company’s official email and WhatsApp channels about offers for goods/services procurement, conditioned on providing a commitment fee ranging from hundreds of millions to billions of rupiah. These offers come from parties claiming involvement in the Hu’u Project development and using identities similar to (or resembling) STM and Vale”.

STM reiterates that PT Abdi Karya Usaha Raya (AKUR), PT STM Vale Hu’u – Vale Global Group (PT STM VH VGG), PT Main Cone Vale Global, PT Vale Global Group (PT Vale GG), and PT SVH – VGG are not affiliated with STM and Vale, and are not involved in managing the Hu’u Project (whether directly or indirectly).

“STM and its shareholders in managing the Hu’u Project uphold the principles of anti-corruption and integrity. Therefore, we never request or stipulate a commitment fee requirement in the goods/services procurement process for any reason. This also applies to the manpower recruitment process,” Cindy emphasized.

Cindy also inform that STM has provided a hotline for the public who wish to verify or report suspicious information or suspected fraud in the name of STM, Vale, and the Hu’u Project through the email address infoSTM1@vale.com or WhatsApp at 0811.1911.0638.

In recent years, STM has also actively and routinely disseminated this information to prevent public losses. In conclusion, Cindy added, “To protect STM’s legal interests, the Company will not hesitate to use all available legal means against anyone engaging in such fraudulent activities,”

Dompu, 5 June 2024 – In celebration of the World Environment Day, PT Sumbawa Timur Mining (STM), holder of the Hu’u Project Work Contract (copper mineral exploration project) in Dompu Regency, West Nusa Tenggara is holding a series of environmental activities in the company’s work area, starting with the ‘Sustain Go to School’ program at SMP Negeri (National Middle Schoo) 1 Hu’u, Dompu Regency and the installation of biopore holes in the Hu’u Project exploration area.

 

“The ‘Sustain Goes to School’ program aims to educate students about the importance of protecting the environment for future sustainability. In this activity, STM representatives together with the school, including students, will plant dozens of tree seedlings around the school area,” says Razky Akbar, Sustainability & External Affairs Manager of STM, in Dompu, Wednesday (5/6).

 

World Environment Day is celebrated every June 5. Led by the United Nations Environment Program (UNEP), the 2024 commemoration has the theme “Accelerating Land Restoration, Addressing Desertification, and Increasing Resilience to Drought.” This theme highlights the importance of immediately restoring degraded land, fighting desertification, and increasing drought resilience. By promoting sustainable land management practices, the initiative aims to revitalize ecosystems, ensure food security, and support the livelihoods of communities that depend on these lands, ultimately contributing to a healthier and more resilient planet. STM also adopts the theme.

 

This year’s World Environment Day is commemorated by STM on Saturday, 8 June 2024, at the Hu’u Project site in Nangadoro. A number of STM employees and contractors’ representatives made dozens of biopore holes installations. According to Razky, the biopore installations also function as water absorption holes which help to fertilize the soil, prevent flooding, and balance water levels in the soil. This step is in line with the theme of World Environment Day 2024.

 

“Vertical holes with a diameter of around 10 – 25 cm can be used to deposit organic waste and stimulate soil biota to create cavities in the soil, thereby facilitating water infiltration into the soil. This is one of the approaches taken by STM to maintain its commitment to the environment. The company continues to rehabilitate land that has been used for exploration activities,” he explains.

 

Razky says further that STM is committed to continuing to do its best for the sustainability of the environment and ecosystem. This is in line with one of the company’s visions, which is to create a sustainable future.

PT Sumbawa Timur Mining (STM), the holder of the Contract of Work for the Hu’u Project (copper mineral exploration project) in Dompu Regency, West Nusa Tenggara, conducted a series of socialization of mineral performance achievements in 2023 and mineral work plans in 2024 to the Central, Provincial and Regency Governments. The socialization activities began in Mataram, the capital of NTB province on 30 April 2024, continued on 7 May 2024 at the Dompu Regent Hall and closed with a meeting with the Minister of Energy and Mineral Resources in Jakarta on 13 May 2024. All were attended by regional leaders, relevant agencies and institutions.   

“This is our initiative, as a form of information transparency to the government. We hope that STM’s investment and exploration efforts at the Hu’u Project receive full support and can run smoothly,” said Yan Fuadi, STM’s Head of Mining Engineering, on Tuesday (5/7).

2024 Work Plan 

Regarding STM’s 2024 work plan, Yan explained that STM will drill approximately 30 drill holes for the purposes of Area Sterilization, Mine Hydrology, Mine Geotech, Resource and Brown Field Exploration. To support exploration drilling activities this year, STM will utilize 5 units of drilling Rigs, including the use of Horizontal Drilling Rig to support Geotechnical studies.

“This year we will continue the geotechnical & hydrological study to increase the amount of data and sharpen the technical analysis as a continuation program that has been started last year, including the horizontal drilling method that will be carried out to support this geotechnical study,” he said.

The Onto deposits, as these mineral deposits are known, offer technical challenges including geological complexity and deposits located 400-600 meters below the earth’s surface. The depth of the Onto deposits makes underground Block Cave mining the only viable mining method for future production operations. The Onto deposits also intersect with geothermal systems, with temperatures ranging from 80 to 110 degrees Celsius, forcing STM to apply appropriate and sophisticated technology to reduce the temperatures and make it feasible for humans to work underground in the future.

In addition to focusing on Geotechnical and Hydrogeological studies, Yan said STM will also carry out other important activities this year, such as increasing the confidence in Onto’s mineral resources and completing the Brown field and regional exploration program to look for other prospects besides the Onto deposits. There are also other planned exploration support activities to be carried out this year, including drill site preparation and rehabilitation, helicopter activities, supporting infrastructure development, and maintenance of exploration access roads.

2023 Work Performance 

Throughout 2023, PT Sumbawa Timur Mining has conducted engineering (technical) studies in the Pre-Feasibility Study stage. The activities carried out include completing the exploration drilling interval to increase resource confidence, conducting geological, geohydrological (Pumping test hole), geochemical and geotechnical studies by operating 7 rigs in the exploration area.

On the same occasion, STM also conveyed the progress of the preliminary survey and geothermal exploration assignment, with the results showing the potential for electricity generation reaching 60 MW. Yan said, “If it is realized, STM will be the only copper mining company powered by its own geothermal power source. With the support of electricity from renewable energy, it will certainly contribute to efforts to reduce carbon emissions in Indonesia.” STM is currently participating in the limited tender process for WKP Hu’u Daha to obtain a Geothermal License from the Directorate General of New and Renewable Energy (EBTKE).

STM also conducts regular and more coordinated environmental management and monitoring, and implements Community Development programs.

Community Relations Manager, Ulya Defretes said that STM also ensures the sustainability of environmental protection activities, mining safety, human resource development, and community development and empowerment. The company will continue its Impactful Community Development activities with three program focuses, namely strategic partnerships, village participation program, as well as donations and sponsorships.

“Some of STM’s flagship empowerment programs in 2023 are cataract surgery and eye examinations with beneficiaries reaching 3,211 patients. There are also 100 scholarships for D1 Heavy Equipment Engineering students, 40 Prestasi Scholarships for Dompu Regency students of various majors, and completion of the basic literacy program for 148 learning citizens,” he said.

Regarding donations and sponsorships, Ulya explained that it is done by considering proposals from residents and the benefits of the program. The community development and empowerment program covers health, education, economic empowerment, institutional, infrastructure, environmental, social and cultural sectors.

“We want to continue to promote the involvement of all stakeholders in our activities and make a positive contribution to regional development in West Nusa Tenggara. We hope that the ongoing cooperation with the local government and the people of West Nusa Tenggara can be even closer to achieve sustainable development,” he ended.

The forestry program covered by the MoU includes forest patrols and surveillance in the STM PPKH area, forestry regulation awareness campaigns, wildfire prevention, the NTB Green program, installation of forestry information boards, as well as assistance and supervision of STM’s forestry programs.

The MoU signing was attended by representatives from DLHK NTB, the Department of Sustainability, and Government Relations at PT STM. The event concluded with the endorsement of the MoU between the Morowali and Toffo Pajo Soromandi (Topaso) Forest Area Strengthening Agency (BPKH).

Forest Management in the STM PPKH Area

STM has been the holder of PPKH since 2010. PPKH is essential as it grants permission to enter forest areas for mineral exploration activities. The goal is to strike a balance between forest conservation and development. “Striving for a balance between forest conservation and operational mineral mining development is one of our primary goals. As a result, we have implemented a series of sustainable forestry management practices with a comprehensive approach since acquiring the Forest Area Utilization Agreement (PPKH),” explained Razky. This forestry management encompasses land opening planning, tree management system implementation, forest seedling care, post-land opening rehabilitation, and reclamation activities.

Over the past 5 years, the post-land opening rehabilitation and reclamation efforts have successfully planted over 13,500 trees. The planning for these activities begins with technical design documents prepared by STM’s forestry team. These plans serve as a guide to ensure rehabilitation objectives are met.

In addition to the forestry management practices, STM conducts routine assessments to mitigate the risk of fallen trees among mature plants within work areas or near supporting facilities. The physical strength of trees is influenced by factors such as age, damage caused by pests and genetics, and weaknesses in internal stem structures. This means that trees may not be as robust as they appear. STM utilizes a resistograph to provide comprehensive information about tree conditions. This tool can detect internal damage without the need to fell or harm the tree. This information enables STM’s forestry team to evaluate and monitor the condition of trees around the camp and operational facilities.

“May today’s signing of the MoU further enhance STM’s efforts and achievements in managing its PPKH area in tandem with the growth of the Hu’u Project,” concluded Razky.
