In this regard, this study uses annual data spanning from 1980 to 2021 and employs advanced nonlinear econometric techniques, including Kernel-based Regularised Least Squares (KRLS) and Quantile-on-Quantile Regression (QQR), to capture heterogeneous relationships across the growth distribution. According to the findings, Ghana simultaneously experiences both blessings and curses in terms of resources across various sectors. Specifically, mineral rents and oil rents exhibit positive growth effects, while forest rents and natural gas rents demonstrate negative impacts. Financial development shows threshold effects, influencing growth only beyond certain maturity levels, while urbanisation consistently drives growth across all quantiles. Trade openness exhibits conditional relationships with adverse effects at lower development stages that improve at higher stages. Furthermore, the Granger causality test findings reveal bidirectional relationships between urbanisation and economic growth, as well as unidirectional causality from economic growth to financial development. These results have important policy implications, particularly for Ghana's prospects of transforming resource curse sectors into blessing sectors through differentiated governance strategies. Considering the key findings, the Ghanaian government should strengthen regulatory frameworks and transparency mechanisms in curse sectors (forest and natural gas) by adopting institutional arrangements similar to those successfully implemented in the blessing sectors (mining and oil). Further, to maximise growth benefits, the government should pursue sequenced financial sector development, recognising threshold effects. It should carefully stage trade liberalisation to ensure domestic industrial competitiveness and sustain urban development investments. Additionally, implementing balanced regional development strategies will address urban-rural disparities and ensure inclusive growth across Ghana's diverse economic landscape.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"110 ","pages":"Article 105766"},"PeriodicalIF":10.2,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145416741","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}

Located near the shores of Lake Superior in the Upper Peninsula of Michigan, the mine faced significant opposition in the beginning of the project. Community members mobilized against the mine's potential for environmental pollution, the impacts of its proposed transportation corridors, and the possible destruction of a culturally significant site. Informed by 24 interviews with political, corporate, economic, and social leaders, site visits, and an in-depth analysis of literature, this article examines the shift in community perceptions of the mine, from opposition to conditional acceptance. We introduce the concept of post-opening acceptance to describe the slow acceptance of industrial infrastructure, in this case a mine, that emerges during the operations phase, despite opposition earlier on. Post-opening acceptance of Eagle Mine was achieved in part, through community-based environmental monitoring and community economic and educational engagement initiatives. However, this acceptance remains contingent on the company's sustained performance, including the absence of acute and chronic environmental impacts, continuous community support, and a visible and accessible presence. This research brings new layers to the SLO and CSR scholarship. It places post-opening acceptance between the consensual approach that mining companies often describe in their community relationship efforts and the most conflictual community-company interactions that have long defined the extractive sector.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"110 ","pages":"Article 105760"},"PeriodicalIF":10.2,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145416742","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}

Miners report arrests, extortion, destruction of equipment, and physical abuse, reinforcing widespread perceptions of corruption and bias shaped by social and political connections. To explain this dynamic, the study introduces the Informal Mining Repression Cycle, which illustrates how military interventions fail to deter informal mining, entrench social and economic inequalities, and sustain its persistence. Many miners, facing unemployment and lacking viable alternatives, return to mining despite repeated crackdowns. Military enforcement is perceived as selective, inconsistent, and influenced by bribery and favoritism. Those without connections face harsher treatment, while individuals with political or financial backing often avoid sanctions. The findings highlight the limitations of militarized responses and point to the need for transparent, accountable, and development-oriented approaches.

In this paper, we examine the link between innovation in these technologies and their material inputs, assessed in terms of mineral occurrence in a sample of 33,036 full-text battery patents published from 2000 to 2021. Our findings, which cover 19 battery technologies, show that, on average, battery technologies increasingly rely on critical minerals. The analysis further reveals a rich tapestry of critical minerals beyond the conventional set of key battery minerals, namely lithium. Evidence shows that chromium, gallium, germanium, molybdenum, niobium, phosphate, silicon, tantalum, tellurium, titanium, and zirconium are all growing in relative importance. Analysis of battery technology specialisation profiles and patterns further highlight inventor countries’ critical mineral needs. While the United States has grown more specialised in sodium-ion batteries, China shows a relative advantage in magnesium-ion, sodium-ion and lithium-ion batteries. Significantly, these patterns similarly reflect diverging paradigmatic shifts in battery innovation along a global “North-South” divide. We conclude with a discussion of potential pathways for battery development and propose avenues for further enquiry at the interface of mineral criticality and geoeconomics.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"111 ","pages":"Article 105755"},"PeriodicalIF":10.2,"publicationDate":"2025-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145420412","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}

Drawing on over a hundred interviews and document analysis, we trace how CSR shifted from ad hoc local philanthropy to more professionalised and strategically targeted interventions as companies sought to establish operations over an unusually long exploration period. Using the lens of political CSR, we show how CSR functioned as an anticipatory political practice, through which companies negotiated legitimacy across scales, managed elite relationships, and shaped regulatory space before oil production began. We further demonstrate that CSR operated as political currency, strategically deployed to secure economic and political licences by negotiating with local communities, subnational elites, and national government actors. While companies framed CSR around the ‘social licence to operate’, in practice the economic and political licences took precedence as firms sought to mitigate risk, secure investor confidence, and manage state relations. The findings extend debates on political CSR by highlighting its anticipatory role, its use as political currency, and its implications for governance and benefit-sharing in Africa's contemporary extractive industries.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"110 ","pages":"Article 105756"},"PeriodicalIF":10.2,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145363438","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}

The framework aims to improve ranking sensitivity, mitigate distortion from extreme scores, and offer a transparent, replicable approach for evaluating lawful mining sites according to many sustainability criteria. Twelve sustainability indicators spanning policy, technical, organizational, and environmental dimensions were evaluated utilizing data gathered from 20 business and academic experts. Five legally recognized and geographically dispersed mining sites were assessed: Newmont Golden Ridge Ltd. (Akyem), AngloGold Ashanti (Obuasi), Gold Fields Ghana Ltd. (Tarkwa), Chirano Gold Mines Ltd.(Bibiani), and Cardinal Namdini Mining Ltd. (Bolgatanga). The model demonstrated considerable variations in performance among regions. Newmont Akyem distinguished itself as the highest-performing site because to its strong environmental practices and adherence to regulations, whilst Namdini placed lowest, revealing deficiencies in community integration and environmental management. The sensitivity analysis validated the resilience of the results across several weighting situations.

This paper describes the principle elements of Semi-Mobile In-Pit Crushing and Conveying haulage system (SMIPCC) production scheduling. A mathematical Mixed-Integer Linear Programming (MILP) optimization model was developed to maximize the Net Present Value (NPV) of long-term open-pit mine production scheduling considering the SMIPCC for concurrently transporting ore and waste material. The model simultaneously determines the production schedule while considering the waste and ore semi-mobile crusher's optimum number, location, relocation time, and future positioning. The crusher's capacity and relocation time consumption due to a decreasing production rate are also considered. This approach aims to maximize the NPV and ensure a suitable feed for the processing plant over the mine life, considering all mining and transportation constraints and treating these factors as a joint optimization problem.
