This research combines quantitative environmental evaluations with qualitative socio-economic analysis to determine the dual consequences of gold mining. Research indicates significant environmental degradation, encompassing water contamination, soil erosion, and deforestation, with arsenic and cyanide concentrations in local rivers surpassing WHO and EPA safety limits. Socio-economic evaluations reveal that mining substantially enhances family incomes, accounting for up to 74 % of wages for artisanal miners; yet, these advantages are inequitably allocated. Community surveys reveal discontent with mining companies' practices, specifically insufficient corporate social responsibility efforts and neglect of environmental and social repercussions. Approximately 58 % of respondents had unfavorable attitudes toward mining owing to its environmental and infrastructural consequences. The research highlights the critical need for sustainable mining techniques, more stringent regulatory frameworks, and improved community involvement. Policy recommendations encompass the implementation of sophisticated environmental assessment techniques, the encouragement of alternative livelihoods, and the equitable allocation of resources to harmonize economic growth with environmental and social sustainability. Future studies should use longitudinal studies and comparative analysis across various mining locations to investigate the long-term effects and effectiveness of suggested remedies.

Most mining companies subjectively determine sample quantity and spatial distribution for density estimation. Usually, the density samples are sparser than the grade samples. Fewer samples tend to generate higher uncertainty as less information is available. Although the density has fewer samples, it is correlated positively with iron grades in an iron deposit. However, this correlation between density and grade is not considered to generate density models. In this context, this research aims to reduce the uncertainty associated with density in iron ore deposits by exploring the correlation between grades and density, using this information to create density models. Therefore, the iron grade was used as an auxiliary variable to create density models proposing different multivariate geostatistical techniques. Two cosimulation approaches were proposed. The first one uses simple cokriging to incorporate the auxiliary variable, while the second uses intrinsic collocated cokriging. These two approaches were compared against univariate geostatistical simulation, which ignores the correlation between density and grades. The results demonstrated the effectiveness of incorporating iron grades in density models, observing histogram matching, reproduction of spatial continuity, the possibility of using the E-Type as estimated models, conditional standard deviation reduction and better accuracy plots in ore and waste domains. Also, a mass analysis was performed in ore domains, making evident how consider Fe grades could change what to expect in future. The study concludes that leveraging iron grades significantly reduces uncertainty in density models, providing accurate and reliable models and proposing methodologies that could be extrapolated to estimates, being viable to create density estimated models for more effective mining planning and resource management in iron deposits.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"103 ","pages":"Article 105561"},"PeriodicalIF":10.2,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143679991","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}

Accurate price forecasting can be useful for better budget planning, strategic decision making and portfolio management. To bridge recent developments in time series forecasting with commodity price forecasting, we investigate the performance of a recently prominent framework called global forecasting or cross-learning. Juxtaposed to the local approach, under which one model would be used for each time series requiring forecasts, this framework involves the training of a single (global) model using a set of relevant time series to create future predictions. In our analysis, we assume that incorporating stock prices of mining companies into global forecasting models can enhance the prediction accuracy of aluminum and copper prices compared to traditional forecasting methods. In this direction, we use a pool of auxiliary time series that includes the prices of the two commodities and the stock prices of major companies involved in their production and processing to train global feed-forward neural networks. The models differ in their approach to selecting relevant time series used in training and are either used as standalones or in combination with standard univariate models to forecast the two commodities’ prices 3, 6 and 12 months ahead. The performance of the models is then compared to benchmark univariate (local) models, namely the naïve method, ARIMA, and autoregressive feed-forward neural networks. The analysis suggests that the incorporation of information from different (albeit related) markets achieved through cross-learning is beneficial for forecasting the prices of the two commodities since, for all forecast horizons examined, the models achieving the lowest out-of-sample error were either standalone global models or local-global ensembles.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"103 ","pages":"Article 105558"},"PeriodicalIF":10.2,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143679987","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}

Using longitudinal data (2006–2018) on Chinese listed firms in the mining industry, and based on a series of endogeneity and robustness tests, we observe robust evidence that third-party monitoring can significantly reduce corporate environmental violations in mining firms. Heterogeneity analysis shows that, compared to non-open-pit mining firms, open-pit mining firms show a more pronounced improvement in the impact of third-party monitoring on corporate environmental violations. And compared to non-coal mining firms, coal mining firms are more susceptible to third-party monitoring. Mechanism analysis shows that third-party monitoring works through promoting government environmental enforcement, broader public participation, and firms' disclosure quality.

It is well established that oil price movement impacts both the stock market and wider economy and thus, we examine whether this is also true of the oil VRP. Using monthly US data over the period from 2009 to 2021, we demonstrate the nature of oil VRP predictive power for oil and stock returns, as well as output growth, unemployment, and inflation. Of notable interest, while predictability from the oil VRP series dominates at the one-month horizon and (largely) wanes at over longer time periods, the reverse is found for the stock VRP. These results are robust to the inclusion of additional, established, predictor variables. This indicates that the impact of oil market risk has a more immediate effect on both the stock market and economy, with stock market risk reflecting longer term considerations.
