1. Lack of Diversification - Western Copper and Gold Corporation is primarily focused on the development of its Casino project in the Yukon, which means that the company is heavily reliant on the success of this project. This lack of diversification could be a disadvantage compared to its peers who have a more diversified portfolio of projects.

2. Limited Production - The Casino project is still in the development stage, and it may take several years before the company can start producing gold and copper. This means that the company may not generate any revenue for a while, which could be a disadvantage compared to its peers who are already producing and generating revenue.

3. High Capital Expenditure - The development of the Casino project requires a significant amount of capital expenditure, which could be a disadvantage compared to its peers who have lower capital requirements for their projects. This could put a strain on the company's finances and limit its ability to invest in other projects.

4. Regulatory Risks - The development of mining projects is subject to various regulatory approvals, and any delays or rejections could significantly impact the company's operations. This could be a disadvantage compared to its peers who have already secured regulatory approvals for their projects.

5. Market Risks - The prices of gold and copper are subject to market fluctuations, and any significant decline in prices could impact the company's profitability. This could be a disadvantage compared to its peers who have a more diversified portfolio of commodities and are less exposed to market risks.
