How Flow-Through Shares Work

Raising money for mineral exploration in Canada can be tough. Flow-through shares offer a tax advantage that helps companies attract investors, especially when combined with federal and provincial tax credits like the Critical Mineral Exploration Tax Credit. These are not grants, but a tax tool that allows exploration companies to pass certain exploration expenses to investors, who then use those expenses to reduce their taxes.

How Flow-Through Shares Work

Flow-through shares are a special way for mining, oil, and gas exploration companies to raise money. The rules are set out in the Income Tax Act (Canada).

Here’s how it works:

• The exploration company sells flow-through shares to investors
• Investors pay for these shares
• The company spends the money on eligible Canadian exploration expenses (CEE)
• The company then renounces (transfers) those expenses to the investor
• The investor uses the expenses to lower their taxable income and may also claim tax credits

This setup is most attractive to people with higher incomes, because they can save more on taxes.

What Expenses Qualify?

Only certain costs count as eligible CEE, such as:

• Geological mapping and sampling
• Geophysical and geochemical surveys
• Diamond drilling and trenching
• Environmental baseline studies for exploration

General office costs, production expenses, and mine development costs do not qualify.

Federal and Provincial Tax Credits

Tax credits make flow-through shares even more appealing for investors. Both the federal government and several provinces offer programs that can be combined with flow-through shares to reduce after-tax costs.

The Critical Mineral Exploration Tax Credit (CMETC)

The Critical Mineral Exploration Tax Credit (CMETC) is a federal tax credit that gives investors back 15% of the eligible flow-through share expenses.

Key points:

• Credit value: 15% of qualified flow-through expenditures
• Who gets it: Investors, not companies
• Eligible minerals: Includes lithium, nickel, cobalt, graphite, copper, rare earth elements, and others on Canada’s critical minerals list
• No double-claiming: You cannot claim both the CMETC and the standard federal Mineral Exploration Tax Credit (METC) on the same expenses

To qualify, expenses must be:

• Spent in Canada
• Properly renounced under a valid flow-through share agreement
• Certified by a qualified person under NI 43-101 standards

Provincial Credits That Stack with Flow-Through Shares

Several provinces offer their own tax credits for flow-through share investors.

Saskatchewan Mineral Exploration Tax Credit

Saskatchewan’s program is one of the most generous:

• Credit value: Up to 60% non-refundable
• Who can claim: Individual Saskatchewan taxpayers (not corporations or trusts)
• How it works: Applies to eligible flow-through share investments
• Approval needed: Companies must be approved by the province

This credit can be used along with federal deductions and credits to further reduce an investor’s after-tax cost.

Other provinces—such as Quebec, Manitoba, and British Columbia—also have their own flow-through share incentives with different rules and rates.

Benefits and Common Mistakes

Flow-through shares offer advantages to both companies and investors, but there are also common pitfalls to avoid.

Why Flow-Through Shares Matter for Companies

While the tax benefits go to investors, companies benefit by:

• Raising money without losing control of their projects
• Attracting investors who want tax savings
• Funding early exploration that banks may not support

For companies exploring critical minerals, flow-through shares can help keep projects moving forward. GrantHub’s eligibility matcher can help you find which federal and provincial incentives fit your exploration plans.

Common Mistakes to Avoid

1. Renouncing ineligible expenses: Only certain exploration costs qualify. CRA audits check this closely.
2. Missing renunciation deadlines: Late or incorrect renunciation can mean investors lose their tax benefits.
3. Thinking companies get the tax credit: Tax credits go to investors. Companies benefit by raising funds more easily.
4. Double-claiming federal credits: You cannot claim both the CMETC and the standard METC for the same expenses.
