1. Lack of Diversification - Northcliff Resources Ltd is primarily focused on the development of the Sisson Tungsten-Molybdenum Project in New Brunswick, Canada. This lack of diversification could make the company more vulnerable to market fluctuations and other risks.

2. Limited Production - The Sisson Project is still in the development stage, and the company has not yet started commercial production. This means that the company is not generating any revenue from its operations, which could impact its financial performance.

3. High Capital Expenditure - The development of the Sisson Project requires significant capital expenditure, which could put a strain on the company's financial resources. This could limit the company's ability to invest in other growth opportunities or return value to shareholders.

4. Regulatory Risks - The mining industry is subject to a range of regulatory requirements, including environmental and safety regulations. Any failure to comply with these regulations could result in fines, legal action, or reputational damage.

5. Competition - Northcliff Resources Ltd operates in a highly competitive industry, with many established players in the market. This could make it difficult for the company to gain market share or attract investment.

6. Dependence on Key Personnel - The success of the Sisson Project is heavily dependent on the skills and expertise of the company's management team and key personnel. Any loss of these individuals could impact the company's ability to execute its strategy effectively.
