Our empirical analysis uses the sentiment data provided by the Thomson Reuters MarketPsych Indices (TRMI) to examine whether investor sentiments collected from various media sources (i.e. traditional news media and social networking sites) would have a heterogeneous impact on the volatility predictions. Overall, our results indicate that both social and news media influence the realized volatility of rare earth equities. More importantly, this effect is positive suggesting that higher media sentiment causes higher volatility. We further observe that the extended HAR models, which include different sentiment measures such as <em>Buzz</em> and <em>Sentiment</em>, tend to outperform the baseline HAR model. Our analysis also concludes that the <em>Buzz</em> index has more predictive contents relative to the <em>Sentiment</em> index.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"107 ","pages":"Article 105655"},"PeriodicalIF":10.2,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144514102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results highlight contrasting outcomes. S4, characterised by minimal regulatory oversight, leads to forest loss exceeding 1000 km<sup>2</sup>, urban area expansion by 200 km<sup>2</sup>, and mining growth of 85 km<sup>2</sup>, illustrating the ecological risks of unchecked development. In comparison, S3 projects forest loss of 914 km<sup>2</sup>, urban growth of 170 km<sup>2</sup>, and mining expansion of 45 km<sup>2</sup>, while S2 predicts forest loss of 753 km<sup>2</sup>, urban growth of 150 km<sup>2</sup>, and mining expansion of 38 km<sup>2</sup>. S1 reflects a balanced growth model with forest loss limited to 631 km<sup>2</sup>, urban growth of 120 km<sup>2</sup>, and mining expansion constrained to 30 km<sup>2</sup>, demonstrating the feasibility of harmonising economic development with ecological preservation through robust land management. Findings emphasize the critical role of land use planning in mitigating the negative impacts of mining and urban expansion. S1 provides a viable pathway for sustainable development, aligning with global sustainability targets by limiting the conversion of ecologically sensitive areas. S2 and S3 indicate a gradual erosion of ecosystem services, while S4 highlights the severe consequences of unregulated growth, including environmental degradation, pollution, and social challenges.

The United States has only one Li mine and commercial refinery, and one Li-byproduct producer in 2024. Projects from exploration to production are classified in four production types: hard-rock mining of Li pegmatites, soft-rock mining of Li clays and sediments, and solution mining of Li brines through evaporative concentration or direct lithium extraction (DLE). This contribution reviews all major U.S. lithium projects to total known (mid 2024) reserves of 0.71 Mt and resources of 27.8 Mt (million metric tonnes contained lithium). Upon this foundation, the political ecology of Li development is analyzed, focused on interconnected environmental impacts and social perceptions. Lithium pegmatite deposits (12 % of reserves; 2 % of resources) have seen open pit mining proposals raise concerns over water quality and landscape disruption. From Li clays and sediments (71 % of reserves; 74 % of resources) controversies have developed over Tribal cultural resources and potential impacts on desert playa ecosystems. Salar-type brines (10 % of reserves; 1 % of resources) supply the sole Li mine through evaporative concentration. High water usage in this method has led to research and development of DLE methods that may enable lithium recovery from geothermal brines and oilfield brines (11 % and 6 % of resources respectively). A summary conceptual diagram of the lithium landscape, highlights interconnected global, domestic, and site-specific factors necessary for responsible U.S. lithium production.

Prior research often examines these challenges in isolation, lacking quantitative causal modeling. This study proposes the Rough Interval-Valued Neutrosophic Decision-Making Trial and Evaluation Laboratory (RIVN-DEMATEL) method to analyze interdependencies among challenges to digital technology adoption in the MI. Integrating rough set theory and neutrosophic logic, RIVN-DEMATEL robustly manages uncertainty in expert judgments, validated via Spearman and Pearson correlation analyses. Key findings identify scalability challenges, cultural inertia, and dynamic operational conditions as dominant causal drivers, which exacerbate effect factors such as resistance to change, cybersecurity risks, and ROI uncertainty. Scalability constraints, for instance, amplify integration issues and data complexity, while cultural barriers fuel workforce resistance. These results underscore the need to address root causes to mitigate downstream impacts. Practical implications include launching modular pilot projects to demonstrate scalability, fostering cultural change through transformational leadership, and implementing reskilling programs to build digital literacy. Moreover, policymakers should establish adaptive regulatory frameworks and offer financial incentives, such as grants for small and medium-sized enterprises (SMEs), to reduce adoption challenges. By synthesizing fragmented insights into a structured decision-support model, this study fills critical literature gaps, providing mining companies, policymakers, and technology providers a roadmap to advance operational efficiency, environmental sustainability, and social responsibility through digital innovation.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"107 ","pages":"Article 105663"},"PeriodicalIF":10.2,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144470831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on these data, commodity price and ASM production development in the 2017–2023 period often show broadly aligned patterns characterized by strong volatility. In recent years, the African ASM contribution to global mine supply has been in the range of 1–12 % for copper, cobalt, lithium and tungsten, and 52–74 % in the case of tantalum. While ASM is thus already making a meaningful contribution to global supply, we present a number of potentially limiting geological, economic and legal factors that impact on the sector's long-term CRM production capacities and the ability by Western mid- and downstream market participants to directly access this supply. These factors include finite ASM-accessible CRM resources and the lack of information concerning the size of these resources, associated financing constraints, competing commodity price developments as well as corporate reputational considerations.
