1. Limited portfolio: Magna Mining Inc has a limited portfolio of mining assets compared to its peers, which may limit its growth potential and ability to diversify its revenue streams.

2. Reliance on a single project: The company's primary focus is on the Shakespeare nickel-copper-PGM project, which means that its success is heavily dependent on the success of this project. This could be a disadvantage if the project encounters any unforeseen challenges or setbacks.

3. Lack of established track record: Magna Mining Inc is a relatively new company, having been founded in 2016. This means that it lacks an established track record compared to its peers, which may make it less attractive to investors.

4. Limited financial resources: The company has limited financial resources compared to some of its peers, which may limit its ability to invest in exploration and development activities.

5. Limited market presence: Magna Mining Inc is a relatively small company compared to some of its peers, which may limit its market presence and ability to compete for contracts and partnerships.

6. Exposure to commodity price fluctuations: The company's success is heavily dependent on the price of nickel, copper, and PGMs, which are subject to significant price fluctuations. This could be a disadvantage if prices fall, as it could impact the company's profitability and ability to fund future projects.
