This study explores the use of machine learning techniques in mineral exploration, specifically in predicting potential locations of gold mineralization in Busia District, Uganda. The study uses geological data, including lithology, geophysical data, geochemical data as well and geographical data to develop and test a predictive model. The results show that the developed model can accurately predict areas with potential gold mineralization, with an accuracy of 87.5%. The study's significance lies in its potential to reduce the time and cost of identifying new gold mineralized areas, contributing to sustainable consumption and production patterns, and promoting sustained, inclusive, and sustainable economic growth. The study recommends validating the accuracy of predictive models, exploring the use of non-geological data sources, monitoring and mitigating the environmental impacts of gold mining, and sharing the findings of this study with relevant stakeholders.

The mining industry grapples with persistent challenges related to ore tracking and security, where theft and unauthorized access to valuable ore containers represent significant financial losses. To address these issues, this project introduces a comprehensive and innovative system designed to precisely track ore placement within containers and proactively prevent theft. The system integrates state-of-the-art hardware components, including RFID authentication modules, highly accurate load cells with HX711 modules, precise GPS tracking modules, and real-time notification capabilities via GSM modules. A robust servo motor-controlled locking mechanism ensures that ore containers remain secure during transport and storage, enhancing the overall security posture of mining operations. The project's modular design not only ensures scalability but also positions it for future upgrades, making it adaptable to the evolving needs of mining operations. By implementing this cutting-edge solution, mining enterprises can significantly mitigate theft risks, reduce financial losses, and elevate overall operational effectiveness.

Extraction, haulage and material and processing of ore to get the end products largely depend on the availability, reliability and effective utilization of equipment. Equipment at Namekara mining company takes 45% of the total production costs, so it is important to keep it in normal working conditions and the availability of equipment high. In this study, failure data for the excavator, wheel loader, scrapper, conveyor belt system and haulage trucks were collected and found haulage trucks with the highest failure rate. Haulage equipment was decomposed into individual subsystems and the transmission, hydraulic dumping and the body subsystems were found to be having the highest failure frequencies. Therefore, the reliability study that has been conducted in this research has based mostly on these subsystems of truck N6.
Failure and mining data for the three haulage equipment used at the mine was collected from maintenance and mining records and has been analyzed. The data was collected over a seventeen-month period of the mine’s operation. Trend and serial correlation tests to validate the assumption of IID (Independent and Identically Distribution) has been conducted. According to the results, the data collected has been found to be independent and identical meaning the occurrence of the current failures does not depend on the previous failures. Therefore, data can be used to model the sub system’s reliability. FMEA for the three critical subsystems was also carried out followed by fault tree diagrams to analyze the equipment from subsystem level to components level in order to ascertain the root causes of failures and come up with improvements have been made. This was done to improve system performance and also gain a thorough understanding of the infant and direct causes of failures to subsystems and components.
FMEA indicated that cylinder seal failure, valve failure, hydraulic pump failure, electrical components failure, clutch failure and failure for the transmission to engage are the most critical failure modes according to their RPN values.
The time between failure (TBF) for the three subsystems was analyzed and tested for distribution estimation and the Weibull distribution had a higher correlation coefficient. The reliability study for the subsystems was therefore done using the Weibull distribution. Reliability plots have been obtained for the three subsystems, preventive reliability maintenance intervals for the three subsystems have been obtained. Maintaining reliability and availability of equipment to meet the production requirement is vital for maintenance and production departments of the mine. To achieve these levels, equipment should be maintained at appropriate times to reduce machine/equipment downtimes as well as reducing maintenance costs.
KEYWORDS:
Reliability centered maintenance (RCM), corrective maintenance (CM), mean time between failures (MTBF), haulage truck, downtime, maintainability.

With the increased environmental pollution and health effects in the communities within and around gold mining areas in Tiira, Uganda, this called for a attention on how this should be mitigated. Both the government of Uganda and some NGOs like the national environmental management authority (NEMA) in conjunction world health organization states it clear that this has been caused mercury disposal from mining activities. Tiira Uganda in eastern Uganda is one of the regions which carryout gold mining including mining on a small scale, where smallest scale miners earn a living. It’s noted that most miners use the mercury amalgamation method in gold processing, which disposes mercury to the environment in large quantities. This is released to the atmosphere, water bodies, soil, among others where human being, animals and fish inhale it and absorb it in their bodies, eat it through food, fish and causes very many healthy effects such damage of the nervous system, kidneys, liver, and immune system.
Never the less it has not stopped on polluting the environment but also causing impurities in the gold processed using mercury amalgamation method.
My project seeks to make research on the investigating the effectiveness of borax n gold purification as it may help give a beginning point for solving the problem. The objectives of my study include determining the gold grades at Tiira gold field; determine the efficiency of direct smelting with borax on my grades and then a lay a strategy of ensuring the miner adoptability to direct smelting wit borax. These are all entailed n chapter one. This chapter also talks about the introduction chic consists of the background of the problem, clearly states objectives, scope of my study and justification.
Chapter two consists of literature review which elaborately shows how different scholars and researchers have successfully conducted research projects about comparison of the gold processing methods particularly direct smelting with borax and mercury amalgamation method commonly used by small scale gold artisanal across the world.
The third chapter is comprised of the methodology applied. Upon collecting additional information from reports and journals, the searcher went ahead to carry out experiments, tests, which required data collection from different fields. here both qualitative and quantitative data was collected to aid in achieving the objectives.
Chapter four talks about the results of all the activities carried out in my project well summarized and respective discussions.it also talks about the conclusion of my project where all the results are summarized, limitation as and challenges faced, which concerns with the pros, that tried to limit and stop the research from gong on smoothly, recommendations where some changes are needed for thing not going on well with in the same field and references showing the various cited articles, journals, among others, who made research about the same or related problem.
