1. Limited portfolio: Abacus Mining & Exploration Corporation has a limited portfolio of mining projects compared to its peers, which may limit its growth potential.

2. Dependence on a single project: The company's flagship project, the Ajax copper-gold project, is its only significant asset, which makes it vulnerable to any adverse developments in the project.

3. High capital expenditure: The Ajax project requires significant capital expenditure, which may strain the company's financial resources and limit its ability to pursue other growth opportunities.

4. Regulatory risks: The company operates in a highly regulated industry, and any changes in regulations or permits may impact its operations and profitability.

5. Exposure to commodity price fluctuations: Abacus Mining & Exploration Corporation's financial performance is highly dependent on the prices of copper and gold, which are subject to significant fluctuations.

6. Limited diversification: The company's focus on copper and gold mining limits its diversification into other commodities, which may expose it to risks associated with a single commodity.

7. Limited geographical diversification: The company's operations are primarily focused in Canada, which may limit its exposure to other mining jurisdictions and opportunities.
