This study evaluates the revalorization potential of Tailings Deposit I at La Cienega (northern Peru) through a comprehensive methodology that integrates geochemical and mineralogical characterization with geostatistical modeling, in support of circular economy frameworks and resource governance. A total of 68 samples from drill cores and trenches were analyzed, focusing on strategic elements such as silver (Ag), lead (Pb), molybdenum (Mo), copper (Cu), antimony (Sb), zinc (Zn), cadmium (Cd), scandium (Sc), and indium (In). Average concentrations were found to be 2293.60 ppm for Pb, 719.61 ppm for Zn, and 98.65 ppm for Cu, along with spatially structured trace levels of In (0.14 ppm) and Sc (9.00 ppm). Ordinary kriging modeling yielded high correlation coefficients (R &gt; 0.8) for Cu, Cd, and Sc, enabling robust three-dimensional estimation of recoverable resources. Mineralogical analysis identified dominant phases such as pyrite and arsenopyrite, along with secondary minerals like jarosite, which influence metal availability. The results underscore the dual character of the deposit as both an environmental liability and a latent strategic asset. Within the context of Peru's evolving institutional and regulatory framework including the MINEM–INGEMMET agreements and the roadmap toward a circular economy in mining this study provides key technical evidence to support sustainable reindustrialization policies. The selective recovery of critical metals and mitigation of toxic elements position the La Cienega deposit as a replicable case of circular mining and integrated resource governance.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"110 ","pages":"Article 105746"},"PeriodicalIF":10.2,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145097188","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}

Asymmetries arise between original populations in remote places and these corporations, as backed by military and civilian representatives of sovereign governments. Our aim is to elevate local voices on the impacts of mining, identifying and distinguishing the most acute impacts and opening them to criticism. Our study is set on New Guinea, in the ancestral territory of the Mimika People, speakers of <em>Akwere Kamoro</em>. A south-north corridor through that territory affords a mining corporation access from the sea to mineral deposits they are extracting in a neighbouring, mountainous territory. To critique the mining activities and their impacts we analyse qualitative data obtained from members of the Mimika People who recount their experiences and emotions about the mining corporation's 60-year presence.</div><div>We find that the mining has brought changes in longevity and modernity (e.g., epitomised in knowledge and skills, goods, services, amenities and infrastructure) which the Mimika People see as positive. Conversely, they have endured far greater negative impacts. These impacts are territorial, demographic, ethnonymic and culturally genocidal in nature. They include upheaval and disemplacement, because of being in the way of the mining and through being greatly outnumbered in what they continue to regard as their own land. The Mimika People now feel like strangers to that land, in the sense of their surroundings changing so thoroughly that it is like having unwillingly resettled in a different place. Further sources of discontentment pertain to their identity and severalty as Mimika People, and their lifeways, autonomy and sense-making capability. By bringing out how acutely these impacts are felt, our study demonstrates that socio-environmental justice relates to physical and emotional circumstances, including discontentment from feeling unjustly treated. Our findings have policy implications. Hearing the perspectives of original populations brings economic, legal, ethical and moral benefits. Giving a voice to the otherwise unseen, unheard and unconsidered can avoid or mitigate wrongs from decisions and actions of far more powerful others. Through that voice, these others can be held accountable for specific consequences and externalities of corporate mining activities.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"110 ","pages":"Article 105758"},"PeriodicalIF":10.2,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145417303","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}

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}

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}

In this process, the study constructs systemic risk time-series for all markets using the Mahalanobis Distance methodology. By transforming raw data into wavelet D6 signals, long-term time-series are generated. Both raw and wavelet-based data are then integrated into a smooth transition regression model to assess nonlinear spillover effects over different time horizons. The findings reveal that precious metal markets are exposed to risk spillovers from industrial metals, energy markets, and stock markets, but only in the low-volatility regime and over the short term. In contrast, industrial metals experience spillover effects across both low- and high-volatility regimes within the short-term horizon. The most pronounced spillover effects originate from BRICS stock markets to industrial metal markets during periods of low volatility. In the long term, the results indicate that risk spillovers from industrial to precious metals become more prominent, suggesting that both markets are heavily influenced by broader economic cycles.

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.

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.
