However, the more individuals develop environmental consciousness, the more they use biomass, which is beneficial to the environment; at the same time, they use less gas, which could be harmful, since gas is cleaner than coal. Contrary to our expectations, we find that increased individual ambidexterity leads to higher CO2 combustion (both total emissions/number of people and per ton of lime) and lower biomass use in kilns. Therefore, our results indicate that individual ambidexterity is harmful to environmental performance. First, we contribute to the microfoundations perspective by showing that individual environmental consciousness does not directly lead to better organizational environmental performance. Second, we reveal that individual ambidexterity can have negative environmental effects, challenging the view that it always supports sustainability.

These steps are critical to aligning disclosure practices with the mining industry's environmental, financial, and social risk profile. This study aligns with disclosure legitimacy theory, which posits that firms disclose information to legitimize operations in high-risk sectors, and impression management theory, which explains the prioritization of aspirational narratives in voluntary frameworks.

Drawing from our qualitative research, findings highlight that women's involvement in different stages of the mineral transportation chain from the extraction of the mineralized rocks (e.g. gold ore) to the crushing, shanking (i.e. sieving), milling, and washing centers are unremunerated, thus revealing socio-historically and structurally embedded dynamics of women's livelihoods, economic exploitation, and dimensions of “gendered sympathy” towards women in ASM settings. Findings also reveal that rural poverty causes increasing feminization of ASM operations, resulting in women's surplus labor that further produces several pathways for economic exploitation and unsafe working environment. Our inquiry showcases that intersectional factors (such as age, social networks, shanking experience, and ethnicity) shape women's access to transportation and processing roles as mining livelihoods to advance their economic independence and overall well-being. In exploring the above issues, we raise questions about women's role in the mineral transportation chain, particularly those related to economic exploitation (e.g. shanking) and the need for gender-sensitive on-site formalization policies.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"107 ","pages":"Article 105608"},"PeriodicalIF":10.2,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144253428","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 study employs an exploratory research approach, integrating field observations, interviews, document analysis, geological mapping, GIS modeling, and mineral economic evaluation. Findings indicate that phyllite mining represents a significant source of mineral revenue with the potential to drive economic prosperity and national development—provided miners undergo formalization. The industry has created thousands of jobs, stimulated local commerce, and generated substantial revenue for landowners and miners, aligning with the anticipated economic contributions of mining projects. Economic analysis suggests that mining a phyllite deposit spanning just 0.2 square kilometers in the Tarkwa mining district could yield over US$2.3 billion. Further investment in exploration could identify additional reserves, enhancing the industry's long-term economic viability. Despite its economic potential, regulatory challenges threaten the industry's sustainability. Pragmatic and accessible regulations are essential to formalizing miners and ensuring compliance with standard mining practices. Post-formalization strategies, such as miner education and training, stringent regulatory enforcement, routine site monitoring, and penalties for noncompliance, are critical to maintaining sustainable operations. These measures will help align mining activities with environmental, social, and governance (ESG) principles while promoting long-term industry resilience.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"107 ","pages":"Article 105642"},"PeriodicalIF":10.2,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144231451","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}

We consider five precious metals, namely, gold, silver, platinum, palladium, and copper to analyse the unique and market risks associated with each as well as construct optimum weighted portfolios using them in different combinations. We find that including a safe haven in a portfolio is a necessary condition to minimize risk but is in no way sufficient. Both gold and silver exhibit safe haven property but an optimum portfolio containing gold and copper offers a higher hedging effectiveness than that offered by an optimum portfolio containing either gold or silver. In fact, copper when combined in an optimal ratio with other precious metals, offers way better hedging effectiveness than other metal-market portfolio combinations.

However, by independently optimizing these schedules, temporal and spatial scheduling misalignment between consecutive schedules occurs and can lead to lower mining project net present values (NPVs). Therefore, it is important to integrate these schedules for improved scheduling alignment. Accordingly, this paper developed a mixed integer programming (MIP) model that integrates LT and MT production schedules to improve scheduling alignment between LT and MT schedules compared to separately optimizing the schedules. The model was solved using a genetic algorithm (GA), which is a stochastic algorithm. The combined MIP model and GA approach was tested on a Geovia Surpac® block model and generated a 2.20 % higher NPV than for the isolated LT schedule. Using the same input parameters on MineLib, the approach was validated by comparing its results to the best-known feasible linear programming (LP) relaxation solutions obtained using a TopoSort heuristic algorithm. For the Newman, Zuck Small and KD block models, the approach generated comparable NPVs, which were 4.90 % lower, 10.90 % higher, and 2.36 % lower, respectively. However, for the four block models, the approach achieved 100 % temporal alignment between LT and MT production schedules, while the isolated schedules had temporal misalignment ranging between 86.22 % and 105.47 %. Therefore, this paper's contribution is on incorporating temporal and spatial alignment between LT and MT production schedules to achieve LT objectives at the MT horizon.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"106 ","pages":"Article 105629"},"PeriodicalIF":10.2,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144190449","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}

Our findings reveal that extreme price shocks in major metals are the most disruptive to power system development; minor metal disruptions, taken together, can also have an equal impact when strictly unavailable. In response, the system adapts by prolonging the operation of existing capacity rather than investing in new infrastructure, thereby exacerbating reliability, economic, and environmental outcomes.

One of the key issues is the determination of the optimal cut-off grade that ensures economic viability. Nickel, as one critical commodity in the renewable energy supply chain, adds another layer of complexity, as its prices fluctuate in uncertain market conditions. These price fluctuations further intensify the challenge of selecting the most economically viable cut-off grade. This research develops a cut-off grade optimization model in an open-pit mining of laterite ores, as the main source of nickel commodities. The proposed cut-off grade model considers two product options, i.e. pure nickel and ferronickel. The uncertainty in selling prices is presumed to follow to the Geometric Brownian Motion (GBM) function. The cut-off grade model is mathematically formulated and analytically solved using derivatives analysis to achieve the global optimal solution. There are two scenarios to be analyzed, which include deterministic and stochastic scenarios. Numerical examples indicate that the proposed model can effectively optimize the cut-off grade value to obtain the maximum profit for both scenarios. An analysis of three scenarios—most likely, pessimistic, and optimistic—shows that fluctuations in selling prices significantly affect both profit and Net Present Value, with the effect amplifying at lower optimal cut-off grades. This finding highlights the importance of flexible decision-making in mine planning to maintain financial stability under the presence of market uncertainties.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"106 ","pages":"Article 105630"},"PeriodicalIF":10.2,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144168265","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}
