Follow up Prompts

After an initial prompt, say “evaluate Agnico”, consider expanding the conversation based on the results. The “context window” (hidden information loaded to the chat session) should be full of all the nitty gritty audited SEC financials and geologic data from the company. Take advantage…

Do: Critique the result with a fine tooth comb. LLM will usually self correct when prompted if an error has been made.

Do: Ask follow up questions for a detailed review, particularly on outliers. Why did you give a low score on “Share Structure”?… or “Open the 13F and summarize the last years insider buying and selling”

Do: Try this, as a followup. Paste the appropriate one of these sensitivity tables and ask the model to populate based on its context window. You should get some positive results

Don’t: Make and investment decision without proper follow up and vetting of the results. This only takes minutes or even seconds. Make a habit!

## Appendix B: Key Financial Formulas

### Basic Valuation Metrics
```
% Return = (New Value - Old Value) / Old Value × 100
Market Cap = Share Price × Fully Diluted Shares
Enterprise Value = Market Cap + Net Debt
```

### Profitability Analysis
```
EPS (Earnings Per Share) = Net Profit / Shares Outstanding
PE Ratio = Share Price / EPS
Free Cash Flow = Net Income + Depreciation - Capital Expenditures
Free Cash Flow Multiple = Market Cap / Free Cash Flow
```

### Mining-Specific Valuations
```
Cash Cost Per Ounce = (Operating Costs - By-product Credits) / Ounces Produced
All-In Sustaining Cost = Cash Cost + Sustaining Capex + Corporate G&A
All-In Cost = All-In Sustaining Cost + Depreciation + Taxes + Royaltes and Fees + Finance Charges + Working Capital + Impairments + Reclamation or remediation + Exploration, development and permitting
Resource Valuation = Resource Ounces × Metal Price × 10%
Quick Market Cap Estimate = Resource Ounces × $250 (for gold)
```

### Growth and Development Analysis
```
Future Market Cap (Reserves) = Annual Production × (Future Metal Price - AISC) × Multiple
Future Market Cap Growth = (Future Market Cap - Current Market Cap) / Current Market Cap
NAV Per Share = Net Asset Value / Fully Diluted Shares
```

### Financial Health Metrics
```
Debt Coverage = Free Cash Flow / Net Debt
Current Ratio = Current Assets / Current Liabilities  
Working Capital = Current Assets - Current Liabilities
Return on Assets = Net Income / Total Assets
```

## Data Quality Audit Framework

### Data Quality Score Components (1-10 Scale)

#### 1. Accuracy Score (1-10)
**Measures**: Factual correctness and source reliability
- **10**: All facts verified through multiple primary sources (SEC filings)

- Confidence Weight: 100%

### SECONDARY SOURCES (Ranked by Reliability)
1. **Rick Rule** - Confidence Weight: 90%

## Audit Check Protocols

### Pre-Analysis Verification
1. Cross-reference all financial data with SEC filings
2. Verify management claims against regulatory disclosures
3. Check resource estimates against NI 43-101 technical reports
4. Validate production data against quarterly/annual reports

### Real-Time Hallucination Detection
- Flag unsupported numerical claims
- Identify inconsistent data points across sources
- Detect impossible or contradictory statements
- Verify all quoted metrics and ratios

### Sycophancy Assessment Criteria
- Excessive use of superlatives without supporting evidence
- Failure to mention obvious risks or challenges
- Overemphasis on positive aspects without balance
- Promotional language inconsistent with factual analysis

## The Enhanced 10-Factor Valuation System

Each factor now includes:
- **Base Score** (1-10): Traditional Durrett scoring
- **Data Quality Adjustment**: Score modification based on source reliability
- **Audit Flags**: Identified issues requiring attention
- **Confidence Level**: Overall reliability of factor assessment

#### Example Enhanced Factor Scoring:
```
Factor 1: Properties/Ownership
Base Score: 8/10
Data Quality Adjustment: -0.5 (secondary source heavy)
Audit Flags: Resource estimate from company website only
Confidence Level: 85%
Final Adjusted Score: 7.5/10
```

## Comprehensive Data Quality Score Calculation

### Overall DQS Formula:
```
DQS = (Accuracy Score × 0.5) + (Hallucination Risk Score × 0.3) + (Sycophancy Risk Score × 0.2)
```

### Risk-Adjusted Investment Score:
```
Final Investment Score = (10-Factor Score × DQS/10) × Confidence Multiplier
```

### Confidence Multiplier Based on Source Mix:
- 90%+ Primary Sources: 1.0
- 70-89% Primary Sources: 0.95
- 50-69% Primary Sources: 0.90
- 30-49% Primary Sources: 0.85
- <30% Primary Sources: 0.75
