1. Limited geographical diversification - Radius Gold Inc operates primarily in Mexico and Guatemala, which exposes the company to political and economic risks in these countries. This lack of diversification also limits the company's growth potential.

2. Small market capitalization - Radius Gold Inc has a relatively small market capitalization compared to its peers, which may limit its ability to attract institutional investors and access capital markets.

3. Limited production - The company does not have any producing mines and relies on exploration and development projects to generate revenue. This makes the company more vulnerable to fluctuations in commodity prices and exploration risks.

4. High exploration costs - The company's exploration costs are relatively high compared to its peers, which may impact its profitability and ability to generate positive cash flows.

5. Limited track record - Radius Gold Inc has a limited track record of successful exploration and development projects, which may make it more difficult to attract investors and secure financing for future projects.

6. Dependence on joint venture partners - The company often partners with other companies to fund exploration and development projects, which may limit its control over these projects and impact its ability to generate returns.

7. Limited resources - The company has limited financial and human resources compared to its peers, which may impact its ability to compete effectively in the industry.
